Groups

so 6/84 x 100 = 7.14% decrease in weight

Edited by:"Mrs.Z" 23rd Oct 2010divide 8 by 76

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

Aww so it is, think i just need to go sleep

The numbers are right though

Edited by:"Mrs.Z" 23rd Oct 2010Sorry 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
