A. 88
B. 24
C. 100
D. 96

4. Which one of the following statements expresses a true proportion?
A. 3:4 = 9:12
B. 2:1 = 1:2
C. 7:9 = 8:9
D. 54:9 = 6:3

Answer 1

A

Explanation:

9 divided by 3 gives 3

12 divided by 3 gives 4

therefore 9:12 is equal to 3:4

Answer 2

Explanation:

3)Total no of people surveyed = 400

Percentage of people preferred WCLM = 24%

Hence no of people who preferred WCLM = 24(400)/100

=96

4)

3:4 =9:12 is true since when simplified both are equal

B is not right 2:1 cannot equal 1:2 as ratio is not commutative

c is not right as they are not equal when simplified

D is not right since when we divide left side by 9, we get 6:1
