Question

Determine if the following are in proportion 8,10, 16 ,20.

Answer 1

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,

8 : 10 : : 16 : 20

Extremes = 8 and 20

Product if extremes = 8 * 20 = 160

Means = 10 and 16

Product of means = 10 * 16 = 160

So, we conclude that ;

160 = 160

∴ Product of extremes = Product of means.

Hence, the given set of numbers are in proportion.
