Y:2,4=3:6

To determine if the ratio y:2 is equal to the ratio 3:6, we need to simplify both ratios and compare them.

First, let's simplify the ratio y:2: y:2

Next, let's simplify the ratio 3:6: 3:6 = 1:2

Now we can compare the simplified ratios: y:2 = 1:2

Since the simplified ratios are equal, we can conclude that y:2 is indeed equal to 3:6.
