A shop has 12 bags of crisps. It sells one-quarter of the bags. How many bags of crisps did the shop sell?

In this problem, we’re told about a shop. And inside the shop, there are 12 bags of crisps. We’ve got a little image of those crisps at the bottom of the question. And the way the crisps have been drawn is quite helpful to us. We can see there are four columns and there are three bags of crisps in each column. We’ll come back to this in a moment. The question tells us that the shop has sold some of the bags. We’re told that it’s sold one-quarter of the bags.

Let’s remind ourselves of what one-quarter of something is. When we find one-quarter, we split it up into four equal parts. And that doesn’t matter if it’s a shape or an amount of crisps in a shop, we still to find one-quarter, need to split it up into four equal parts. We divide the whole amount by four. So to find one-quarter of 12 bags of crisps, we need to divide this amount by four too.

We need to split up the bags of crisps into four equal groups. This is where the picture becomes helpful. The crisps are already split into four equal groups because we can see four separate columns. So how many bags of crisps are in one of these columns? There are three bags of crisps in the column. 12 split into four equal parts equals three.

One-quarter of 12 is three. And so, if the shop sells one-quarter of 12 bags of crisps, it sells three bags.
