Question

determine if the numbers 36,60,30 and 50 are in proportion

Answer 1

$\frac{36}{60} \times \frac{30}{50}$

$36 \times 50 = 60 \times 30$

$1800 = 1800$

$hence \: proved \: product \: of \: mean \: of \: equal \: to \: the \: product \: of \: extreme$

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,

36 : 60 : : 30 : 50

Extremes = 36 and 50

Product if extremes = 36 * 50 = 1800

Means = 60 and 30

Product of means = 60 * 30 = 1800

So, we conclude that ;

1800 = 1800

∴ Product of extremes = Product of means.

Hence, the given set of numbers are in proportion.
