Ratios are a useful way of expressing the proportion of quantities in a mix, without having to specify the entire quantity. So if I’m making ham and cheese sandwiches (with one slice of ham and one of cheese per sandwich) I will require two slices of bread for every one slice of ham and one slice of cheese. I need slices of ham, cheese and bread in the ratio 1:1:2 – and that ratio never changes regardless of the total number of sandwiches required.

Typically in questions, you will be given an original amount that must be split into a given ratio.

Simple as that. When the ratio quantities are larger and when the original amount is less of a whole number these questions become more of a challenge in division, so once again the basic skill of times-tables and division becomes important. Consider a second version of this question...
