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

Answer 1

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

We have the ratio 12 : 9 and we want to express it as the ratio 4 : x.

To find the value of x, we can set up a proportion:

12/9 = 4/x

To solve for x, we can cross-multiply:

12*x = 9*4

12x = 36

Dividing both sides by 12, we find:

x = 3

So the equivalent ratio is 4 : 3.
