Level 5-6 Numbers - Decimals - Multiplication and Division

After addition and subtraction, multiplication and division are the most common parts of maths. That's true in KS3 Maths just as much as it is in junior school or university. Once you've got the hang of multiplication and division it becomes quite easy - even when working with decimals.

Multiplication and division of decimals is very similar to normal multiplying and dividing of numbers. The one thing you need to be aware of is the placement of the decimal point. It might help you to make a guess as to the answer before you do your calculations. For example, if you multiply 2.3 x 4.01 you know that the answer will be something like 9, not 92,000! Better still, learn the rules for placing decimal points in multiplication and division - that will make the problems much easier to solve.

In the following quiz I recommend that you estimate your answers before you do your calculations - that should help! Good luck.
