Question

Select all ratios equivalent to 4:9.
44:99
7:12
81:36

Answer 1

44:99

Explanation:

44:99 can be reduced by 11 to 4:9

7:12 is not equivalent because it is already reduced to its simplest term. But when multiplied by 2, you get 14:24

81:36 can be reduced to 9:4 which is not the same as 4:9. It would be if it was flipped.

For example;

Take 1:2 and 2:1

For every 2 boys, there is 1 girl. If the numbers were flipped it'd be for every 2 girls, there is one boy. So you see, they are not the same.

Answer 2

44:99

Explanation:

Once you simplify all possible answers, only 44:99 matches 4:9, since 44 divided by 11 equals 4, and 99 divided by 11 equals 9
