Answer 1

4:6=2:3
8:12=2:3
yes

Answer 2

Answer :

Yes, the numbers are in proportion.

Step-by-step explanation :

A group of numbers is said to be in proportion if the product of their extremes is equal to product of their means.

Here,

4, 6, 8, 12

Extremes = 4 and 12

Product if extremes = 4 * 12 = 48

Means = 6 and 8

Product of means = 6 * 8 = 48

So, we conclude that ;

48 = 48

∴ Product of extremes = Product of means.

Hence, the given set of numbers are in proportion.
