thirty percent of what number is 120?

• math -

how do u figure that out

• math -

30% = 0.3

Multiply.

• math -

You can set up an equation:

30%= .3, so you'll have

.3x= 120 (where x is the number whose 30% is 120)

x= 120/.3
x= 400

You can check by multiply .3 x 400= 120

So 30% of 400 is 120
