You may have seen numbers placed either side of a colon before, perhaps something like this - 2:1 or 3:1, but what do the numbers mean? Well, we call these ratios. A ratio is the comparison of two numbers or quantities. For example, in a bowl of fruit there are 8 apples and 6 pears. The ratio of apples to pears would be 8:6 (or 4:3 which is equivalent to 8:6). Do you know what the ratio is of pears to apples? Well, we just turn the numbers around. The ratio of pears to apples is 6:8 (or 3:4). Ratios are a great tool which can help us to understand how different amounts compare to one another.
