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