Write the ratio 12:36 as an equivalent ratio of x:3 .(1 point)

5 answers

To find the equivalent ratio of x:3, we need to find a value for x that has the same ratio with 3 as 12 has with 36.

To do this, we set up a proportion:

12/36 = x/3

To find x, we cross multiply:

12 * 3 = 36 * x

36 = 36x

Dividing both sides by 36:

1 = x

Therefore, the equivalent ratio of 12:36 as x:3 is 1:3.
