Fascinating Fact:

A standard guitar has six strings, a multiple of two and three, giving just enough harmony for both maths and music to agree.

In 11 Plus Maths, multiples help students spot patterns in times tables and understand how numbers connect. This knowledge supports work on fractions, ratios, and problem-solving.

Key Terms

Multiple: A number that is the product of another number and a whole number.
Even Number: A number that can be divided by two without a remainder.

A good strategy is to check if one of the given numbers DOESN'T divide. If you can't find one, then that's your multiple. If you do find one, then that's NOT your multiple.
48 isn't divisible by 11, 66 isn't divisible by 4, and 121 isn't divisible by 2, 3 or 4

Which of the four choices is a NOT multiple of ALL the numbers given?
6, 7, 9

[ ]	252
[x]	63

Find multiples of decimal numbers in just the same way as you find multiples of whole numbers: multiply them.
75 and 90 aren't divisible by 12 or 20, while 220 isn't divisible by 7.5, 12 or 15
