Here is the math question that I am stuck on:
It's Pancake Day and Nigel is making a large batch of pancakes to share with friends. His recipe tells him to add 2.5 litres of milk, but his measuring jug only measures up to 500ml and is accurate to the nearest 10ml.
a) What is the maximum volume of milk Nigel could measure out, assuming he is accurate as he can be?
b) What is the minimum volume of milk Nigel could measure out?
We haven't started Upper and Lower bounds in school yet so I'm just doing further work from a workbook but I can't seem to understand this question! Step by step instructions will be greatly appreciated.
