Welcome to this, the second of our very easy Eleven Plus maths quizzes on multiples. By now you should know exactly what multiples are. If not, here’s a reminder:

A multiple is a number that may be divided by another a certain number of times without any remainder. So, 15 for example, is a multiple of 3 and 5 because it appears in both the three-times-table and the five-times-table. Likewise, 12 is a multiple of 2, 3, 4 and 6 because you will find the number twelve in all of those times tables.

If you are in any doubt, just ask yourself ‘does this number appear in that times table?’ If the answer is yes, then you’ve found yourself a multiple. Now. Let’s find out how well you can spot them. But take your time – carelessness costs marks in exams.
