Answer 1

14 % of x is 21

0.14 * x = 21 |multiply by 100

14 x = 2100 |divide by 14

x=150

Answer: 21 is 14% of 150

Answer 2

21 is 40%

21 = 40%x

21=14/100x

Simplify both sides of the equation.

21=7/50x

Flip the equation.

7/50x=21

Multiply both sides by 50/7.

(50/7) * (7/50x) = (50/7) * (21)

x=150

Answer: 21 is 14% of 150.
