Y:2,4=3:6

To determine if the numbers 2 and 4 are proportional to the numbers 3 and 6, we can check if the ratios of the corresponding numbers are equal.

The ratio of 2 to 4 is 2/4 = 1/2.

The ratio of 3 to 6 is 3/6 = 1/2.

Since the ratios are equal (1/2 = 1/2), this means that the numbers 2 and 4 are indeed proportional to the numbers 3 and 6.
