Divide numbers with tenths by a single digit number

Why do we need to divide decimals?

Sometimes, before you can really understand how to perform some number problems, it helps to understand why you need to do them. In the video below, we will look at why you may need to solve a problem such as $13.2$13.2 divided by $4$4.

Let's say there are $4$4 students, and the teacher has $13.2$13.2 hours available throughout the term to provide some extra help with their reading. This division problem can help work out how much each child will be allocated. The answer, in this case $3.3$3.3 hours each, can then be converted to hours and minutes. We won't solve that part here, but you can see how knowing how to solve the division part of this is useful. Oh, by the way, if you want to work on your time problems, you can click here to do that!

Let's work through some similar examples now in the video. Thinking about tenths is really important, as we are looking at whole numbers and decimals.

Now we’ll look at using short division as a way to solve a division with decimals. Short division has less steps than long division, as you do some of the mental maths in your head as you go, which we work through here in Video 2. In this example though, we need to rename some of our digits, just like we would when dividing whole numbers.
