Answer 2

You would do this:

0.40 x 90

So basically all you are doing is dividing 40% by 100, and then timesing it by 90.

Answer 3

you change the percent to a number.

40%= .40

you multiply 90 to .40

90 x .40 = 36.00 = 36

Answer 4

90 X 40% is 36 (90 * 0.4)

to change a # to a % you gotta divide it by 100.

Answer 5

90 x 40%

= 90 x 40/100

= 90 x (40 ÷ 20)/(100 ÷ 20) (= 90 x 40 ÷ 100)

= 90 x 2/5 (= 90 x 0.4)

= 180/5 (= 36)

= 180 ÷ 5

= 36

Answer 6

Do this

40 over 100 times 90.

Simplify the numbers by cutting some zeros , then times and divide.

Works for me, and I got 100% on my latest math test.
