and times the answer by 100

which = 10.526316

yep

8/84 x 100 = 9.5% :)

You divide by 84 because 84 is the original number and you want to find the percentage decrease of that number, not the final figure

Sorry but your numbers are wrong also.

The answer is not calculated using the difference. It's the percentage increase above 76 were 76 is 100%.

It is 84 / 76 * 100 = 110.526% so the difference is 10.526%

10.526% is the answer

Anyway,

Assign A = 84, B =76

percentage change = ((A / b) -1) * 100
