Working
Each percentage question is calculated with a direct formula, then formatted as a number or percent.
15% of 240 = 36
Step 1Percent of a number
(15 / 100) x 240 = 36
Convert the percent to a decimal, then multiply by the base number.
Step 2Part as a percent of whole
(25 / 200) x 100 = 12.50%
Divide the part by the whole to find its share.
Step 3Percentage change
((100 - 80) / 80) x 100 = 25.00%
Positive means increase; negative means decrease.
Further explanation
In 15% of 240, 240 is the whole and 36 is the requested part.
For change questions, the old value is the starting point, so the difference is measured relative to 80.
