7 % means7 / 100

Next multiply to 80

Hence 7 x 80 / 100 =

Cancel down by '10'

7 x 8 / 10

Cancel down by '2'

7 x 4 / 5

Multiply

28/5

Reduce to a mixed fraction

5 3/5 or 5.6 is the answer!!!!

Convert the problem to an equation using the percentage formula: P% * X = Y.

P is 10%, X is 150, so the equation is 10% * 150 = Y.

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

You go back to third grade and learn your multiplication tables and fractions first.

You can figure this out in seconds without math just by using logic.

1) You know it's a multiplication problem because of the word "OF"

7% OF 80

2) You already know that 10% of 80 is 8

3) So the answer has to be "a little less than 8" because 7% is a little less than 10%

4) So you don't even have to calculate where the decimal point goes.

It goes wherever it will give an answer of "a little less than 8"

5) 7×8 = 56 ← This has to be a multiplication problem

6) Now locate the decimal point to make the answer "a little less than 8"

ANSWER:

7% of 80 is 5.6

-------------------------------

Note:

The answer cannot be 56 ← too large -- way more than 8

The answer cannot be 0.56 ← too small -- way less than 8

The answer must be 5.6 ← just right -- "a little less than 8"
