Question

Determine the correct equation used in order to solve the problem "The number 24 is what percent of the number 40?"

Answer 1

The correct equation that represents the expression "The number 24 is what percent of the number 40?" is as shown below;

The the unknown number in percent be 'x'

x percent of number 40 is expressed as;

x% of 40

x/100 of 40

If 24 is equal to the expression above, then the final equation will be expressed as;

24 = x/100 of 40

24 = 40x/100

24 = 0.4x

Rearrange

0.4x = 24

Hence the correct equation used to solve the problem is 0.4x = 24
