Working Out
The problem we are solving is:
Work out the percentage increase between 275 and 561.
Difference is 561 - 275 = 286.
Divide the difference between the original number:
286 / 275 = 1.04.
Multiply by 100 to change to a percentage:
1.04 x 100 = 104%.
This number is positive so we have a percentage increase of 104%.
