An ESTIMATE of 39% of 120
malfutka [58]

ANSWER: 46.8


39% of 120

The word "of" means multiplied. So you will have to multiply 39% x 120

To do that, first step is to change the percent (39%) into a decimal


39% = 0.39  (You move the decimal twice to the left, not right)

There's an invisible decimal behind 9 so ALWAYS move it twice.

= 39(.)⇒ 0.39


Then your final step is to multiply

120 x 0.39


    1 2 0

x 0 . 3 9   ← notice this decimal

_______                    ∨

 1 0 8 0                     ∨

+ 3 6 0 0                    ∨

_______                    ∨

  4 6 8 0          There's an invisible decimal before the 0. Move that decimal two times to                                  the left.   4680(.)⇒ 46.8
