Answer 1

x = 6

In the picture I have explained it pretty well,hope it helps..

Answer 2

Step-by-step explanation:

Given :-

2,x, 5, 15 are in proportion

To find :-

Find x if the numbers 2,x, 5, 15 are in proportion.?

Solution :-

Given numbers are 2,x,5,15

Means = x and 5

Product of means = x×5 = 5x

Extremes = 2 and 15

Product of extremes = 2×15 = 30

We know that

In Proportion, Product of means = Product of extremes

If 2,x,5,15 are in the proportion then

=> 5x = 30

=> x = 30/5

=> x = 6

Therefore, x = 6

Answer:-

The value of x for the given problem is 6

Check :-

If x = 6 then the numbers will be 2,6,5,15

Product of means = 6×5 = 30

Product of extremes = 2×15 = 30

Product of means = Product of extremes

They are in the Proportion.

Verified the given relations in the given problem.

Used formulae:-

• In Proportion, Product of means = Product of extremes
