Worksheet Overview

In this activity, you can use a calculator to answer the questions.



Work out £3.41 + 56p.  Give your answer in £s.



We must NOT work out 3.41 + 56 as one amount is in £s and the other in pence.

The answer is to be given in £s, so we change everything to pence.


56p is the same as £0.56

On the calculator, we add 3.41 + 0.56 = 3.97


The answer is £3.97.  


Note that the answer is not 3.97 but £3.97
