Find the third proportion to 6,8 and 10.

Step: 1

Here a = 6, b= 8, c= x and d = 10.

Explanation:

Given proportion a = 6, b= 8 ,c = x and d = 10.

Step: 2

First, write in proportion form.
\$a/b :: c/d\$ i.e., \$6/8 :: x/(10)\$

Explanation:

Let’s get started! Write the proportion like this: stem:[a/b: c/d]. For instance, you can use \$6/8:: x/(10)\$.

Step: 3

Now, we are finding the third proportion x = \$(6 \times 10)/8\$ = 7.5

Explanation:

We found the third proportion using x = (6 x 10)/8 and got 7.5 as the answer.

Step: 4

So, the third ratio is 7.5.

Explanation:

The third ratio equals 7.5.
