​

Answer 1

Step-by-step explanation:

Given:-

the numbers 8, x, 9 and 36 are in proportion.

To find:-

Find the value of x.

Solution:-

Given numbers are 8,x,9,36 in the proportion.

8:x::9:36

Product of Means= 9x

Product of Extremes=8×36=288

If the numbers are in the proportion then Product of means = Product of extremes

=>9x=288

=>x=288/9

=>x=32

Answer:-

The value of x=32

Proportion:-

Equality of the ratiosis called Proportion.

Rule:-

Product of means=Product of extremes

If a,b,c,d are in the proportion then

a:b::c:d then bc=ad.
