Question

1. Determine if the following numbers are in proportion
15, 25, 30,150
​

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,

5 : 25 : : 30 : 150

Extremes = 5 and 150

Product if extremes = 5 * 150 = 750

Means = 25 and 30

Product of means = 25 * 30 = 750

So, we conclude that ;

750 = 750

∴ Product of extremes = Product of means.

Hence, the given set of numbers are in proportion.
