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 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"
