1. Write the ratio 12:9 as an equivalent ratio of 4:x

1 answer

To find the equivalent ratio, we need to find the value of x that makes the two ratios equivalent.

We can do this by setting up a proportion using the given ratio:

12/9 = 4/x

To solve for x, cross multiply and solve for x:

12x = 4*9

12x = 36

Divide both sides by 12 to isolate x:

x = 36/12

x = 3

Therefore, the equivalent ratio of 12:9 as 4:x is 4:3.
