Ratio And Proportion

Worked Exercise

  1. Muraya and Dan each made 126kg of a mixture of maize and beans. Muraya mixed maize and beans in the ratio 4:3 while Dan mixed maize and beans in the ratio 4:3 while Dan mixed maize and beans in the ratio of 5:4. How many more kilograms?
    1. 2
    2. 3
    3. 4
    4. 6
      Working
      In Muraya’s mixture, maize: beans = 4:3
      maize = Ratio of maize/Total ratio x No of kg
      =4/7 x 126
      72kg
      In Dan’s mixture, maize: beans = 5: 4
      Maize = Ratio of maize/Total ratio x No of kg
      =5/7 x 126
      = 70kg
      Difference = ( 72 - 70 )kg
      = 2kg
      The correct answer is A (2kg)
  2. A rectangular plot measures 12m by 10m.The length of the plot is increased in the ratio 3:2 , while the width is decreased in the ratio 4;5.By what ratio is the area of the plot decreased?
    1. 4:3
    2. 5:4
    3. 6:5
    4. 3:2
      Working
      New length after increase
      3/2 x 12 = 18m
      New width after decrease
      4/5 x 10 = 8m
      Original area before the increase/decrease
      = (12 x 10) m2
      = 120m2
      New area = (18 x 8) m2
      = 144 m2
      New ratio = 144: 120
      = 6 : 5
      The correct answer is C (6: 5).
  3. Gladys keeps hens, ducks, and turkeys. The ratio of hens to ducks is 5:2. The number of turkeys is 35 less than the number of hens. How many turkeys are there if there are 30 ducks?
    1. 105
    2. 40
    3. 75 
    4. 65
      Working
      Hens : ducks = 5 : 2
      Total ratio = 7
      Ducks = 2/5
      Hens = 5/7 of x
      Therefore 2/7 of x = 30
      x = 30 x  7/2
      x = 105 (Total hens and ducks)
      Hens =5/7 x 105
      = 75
      Turkeys = (75 – 35)
      The correct answer is B (40)
  4. Elijah and Paul shared some money in the ratio 5:8.Elijah got sh120 less than Paul. How much money did Paul get?
    1. Sh520
    2. Sh320
    3. Sh200
    4. Sh192
      Working
      Let the amount Paul got be t
      Therefore Elijah got (t-120)
      Therefore t -120 : t = 5 : 8
      t – 120/t = 5/8
      8t – 960 = 5t
      8t – 5t = 960
      3t = 960
      t = sh320
      Therefore Paul got = sh 320
      The correct answer is B (sh320)
  5. A contractor employed 60 men to complete a piece of work in 150 days. How many more days would 50 men take to complete the same work?
    1. 180
    2. 30
    3. 40 
    4. 50
      Working
      60 men take 150 days
      1 man take (150x60) days
      Therefore 50 men will take 150 x 60/50 days
      = 180 days
      How many more? (180 – 150) days
      = 30 days
      The correct answer is B (30 days)
  6. Eighteen men can finish to dig a piece of land in 45 days. How many days would 15 men take to finish the same piece of land?
    1. 54
    2. 2
    3. 9
      Working
      18 men take 45 days
      1 man takes (45 x 18) days
      Therefore 15 men will take 45 x 18/15
      = 54 days
      The correct answer is A (54 days)

Scale Drawing - Class 8 Mathematics Revision Notes

Scale Drawing

Worked Exercise

  1. The distance between two villages is 6.4KM. On the map of the region this distance is represented by a line 1.6 cm long. What is the scale of the map?
    1. 1: 400000
    2. 1: 40000
    3. 1: 4000 
    4. 1: 4
      Working
      Actual distance = 6.4 km
      Drawing length = 1.6cm
      1 cm on the map = 6.4/1.6
      = 4km on the ground
      But 1 km = (1000 x 100) cm
      4km = 4 x 1000 x 100
      = 400000cm
      Therefore scale = 1: 400000
      The correct answer is A (1: 400000)
  2. A rectangular field measures 105 m. On a scale drawing of the field, the longer side is 7cm.What is the measurement of the width on this scale drawing?
    1. 5 cm
    2. 50 cm
    3. 500 cm
    4. 7.35cm
      Working
      7 cm represents 105 m
      1 cm represents (105 ÷ 7)
      Scale used,
      1 cm represents 15m
             ?                  75m
      = (75 x 1)/15
      5cm
      The correct answer is 5cm (A)
  3. The scale on a plan is 1:20. How many cm will represent 1m on this plan?
    1. 50 cm
    2. 50 cm
    3. 5 cm
    4. 2 cm
      Working
      1 : 20 scale means 1 cm on a drawing represents 20 cm on the ground.
      1 cm represents 20cm
         ?                      100cm
      =100/20
      = 5cm
      The correct answer is C (5cm)
  4. A rectangular field measuring 720m by 550m is to be represented on a scale drawing using the scale 1: 10,000. What is the perimeter of the drawing in centimetres?
    1. 0.254
    2. 2.54
    3. 25.4
    4. 254
      Working
      1: 10000 means 1 cm on the map represents 10000 cm on the ground
      If 1 cm = 10,0000cm
      ? = 72,000cm
      = (72000/10000) cm
      = 7.2cm
      If 1cm = 10,000cm
      = 55,000cm
      = ( 55,000/10,000 ) cm
      = 5.5cm
      Perimeter
      MathNotes 11scl1
      P = 2(L+W)
      = 2 (7.2 + 5.5)
      = 25.4 cm
      The correct answer is (C)
  5. The scale of a map is 1: 50000. What is the length of this map of a road 20km long?
    1. 40cm 
    2. 400 cm 
    3. 4000 cm
    4. 4 cm
      Working
      Scale 1 : 50000 means 1cm on the map represents 50000 cm on the ground.
      20 km = 20 x 1000 x 100
      = 2000000 cm
      50,000cm represents = 1 cm
      2,000,000 represents = 2,000,000 ÷ 50,000

    2. 3
    3. 5
    4. 4
      Working 2 (3x – 2 ) = 3x + 8
      Step 1: Open brackets 6x – 4 = 3x + 8
      Step 2: Collect like terms and simplify 6x – 3x = 8 + 4 3x = 12 x = 4

    4. r + s + 300
      Working
      Francis = r
      John = s
      Ouma = r + s - 150
      Total money = r + s + r + s – 150
      = 2 r + 2s – 150
      The correct answer is A (2r + 2s – 150)

Worked Exercise

  1. Find the value of x in the following.
    MathNotes 8geo1
    Working
    X+45+50=1800 (Angles on a straight lines are supplementary i.e. add up to 180º )
    X+95=180º
    X=85º
    The value of x =85º
  2. Find the sum of angle “a” and angle “b” in the figure below.
    MathNotes 8geo2
    Working
    Lines AB and C D are transversals  are Therefore 90+b = 1800
    Co-interior angles - supplementally
    Therefore b=180-90
    B = 90º
    Angle a = 120º - (Corresponding angles)
    Therefore a = 120º
    Sum of a and b
    =120 + 90
    = 210º
  3. Find the size of angle marked A B D in the figure below.
    MathNotes 8geo3
    X+4x+x+30=180º (angles on a straight line are supplementary)
    = 6x+30=180
    6x=180-30
    6x = 150
    X = 25
    Angle A B D =x + 4X
    But x = 25
    Therefore 25 + (4 x 25)
    = 25 + 100
    = 125º

  6. A rectangle measures 6cm by 2½ cm. What is the length of the diagonal?
    Working
    MathNotes 8geo6
    AC2 = AB2 + BC2 [ Pythagoras Theorem]
    AC2 = 62 + 2 ½2
    AC2 = 36 + 6.25
    AC2 = 42.25
    AC = √42.25
    = 6.5 or 6 ½
    NB: The Pythagoras theorem states
    H2 =B2 +h2
    h2 = H2 – b2
    b2 = H2 –h2
  7. In the figure below, A B C is a straight line and B C D E is a quadrilateral. Angle CBD = 620 and lines EB = BD = DC. Line EB is parallel to DC.
    MathNotes 8geo7
    What is the size of angle BDE?
    Working
    Consider triangle BCD (isosceles triangle)
    Therefore base angles are equal
    CBD = 62º
    BCD = 62º
    Therefore, BDC = 180 – 124 = 56º
    Angle CDB = angle EBD [Alternate triangle]
    Therefore EBD = 56º
    Angle BDE =180 - 56/2
    = 62º
    Therefore, BDE = 62º
  8. Find the size of the largest angle from the following triangle.
    MathNotes 8geo8
    Working
    4X – 10 + x – 20 + 3x + 10 = 180 [Angle sum of a triangle]
    8x – 20 = 180
    8x = 200
    X = 25
    4x – 10 = (100 – 10)º
    = 90º largest angle.
