Hello again everyone, here’s some information and help on ratio that a lot of you have been having difficulty with. Watch the Maths Antic video below for a very simple but good explanation of what ratio is and how to calculate using given ratios.
So, ratio is simply comparing one value with another. How much of one thing do we have compared to another thing.
However, as we all know SATs test are not that easy. Ratio becomes more difficult when we introduce proportion. Proportion is where we compare a number in relation to a whole. This is where everything becomes a little complicated, as ratio and proportion are mixed together in SATs questions. You need to have a good understanding of both to enable you to identify which numbers within the worded question you will need to use to formulate your calculation and what operation you will need to carryout.
