**The times tables that you have learnt will help you in this multiples** quiz. A 'multiple' is a number that can be divided exactly by another given number, e.g. 6 is a multiple of 3 because 3 divides 6 exactly two times. In addition, 3.4 is a multiple of 1.7 because 1.7 divides 3.4 exactly two times.

In this 11-plus Maths quiz we shall only be dealing with whole numbers BUT it's a good idea to keep a lookout for multiples when you work with decimals. As a fun experiment see how many numbers you come across today, write them down and find out how many multiples you can find. Doing these kinds of exercises will really help with your knowledge of numbers and Maths.

It's a really easy quiz, so if you don't get 10 out of 10 first time play it again until you do. Enjoy yourself!

A good strategy is as follows: find a likely multiple and check to see if one of the given numbers DOESN'T divide it. If you can't find one, then that's your multiple. If you do find one, then that's NOT your multiple, e.g. 4 doesn't divide 14
