Question

14% of what number is 21

Answer 1

To rearrange it into a proper equation replace ‘of what number’ with ‘x’ and is with ‘=‘
The sentence become
14% * x = 21
Since 14% = 0.14,replace 14% with 0.14 in equation
0.14 * x = 21
Divide both sides by 0.14
X= 21/ 0.14
x = 150

Answer 2

150 is the number

Explanation:

The equation we should set up is from the sentence "14% of what number is 21"
To rearrange it into a proper equation, replace "of what number" with " * x "
and "is" with "="
The sentence becomes:

14% * x = 21

since 14% = 0.14, replace 14% with 0.14 in the equation

0.14 * x = 21

divide both sides by 0.14

x = 21 / 0.14

x = 150
