Question

Increase £180 by 12.5%

Answer 1

£202.50

Explanation:

First convert 12.5% into a decimal by dividing it by 100 to get 0.125.

Then we work out 12.5% of 180 by multiplying them: 180 * 0.125 = 22.5

Then we are increasing so add it back to the original: 180 + 22.5 = 202.5

Because we are using £ we add it back on and add a 0 for the pennies.

Answer 2

202.5

Explanation:

180+180*12.5% or 180*112.5%
