Question

What percent of 150 is 39?​

Answer 1

26%

Explanation:

In a percent proportion, the first ratio is percent/100. We do not know the percent, so we will use a variable: x/100.

The second ratio is part/whole. 39 is the part and 150 is the whole; this gives us 39/150.

This gives us the proportion

x/100 = 39/150

Cross multiply:

x(150) = 100(39)

150x = 3900

Divide both sides by 150:

150x/150 = 3900/150

x = 26

Answer 2

let assume x percent of 150 is 39

so

150 × x % = 39

150 × x/100 = 39

x = 39×100/150 = 26 % answer
