Question
David is doing some DIY. He buys a 2m length of wood. He needs to cut two pieces of wood - one of length 0.6m and one of length 1.02m.
What is the total length of wood that David needs to cut?
You can add zeros to the end of a decimal without affecting its value, so 0.6 is the same as 0.60.
