The third proportion to 36 and 48 is 64.

Given:

36 and 48

To find:

Find the 3rd proportion to 36 and 48

Solution:

To find third proportion, we have to let it as x

When finding third proportion, second number is written in both places of means, so

36:48::48:x

Now, if they are in proportion,

Product of extremes = product of means

36 * x = 48 * 48

36x = 2304

x = 2304/36

x = 64.

Hence, third proportion is 64.
