This is our second page on ratio and proportion, an area of maths which is less well covered than the traditional four rules but nevertheless involves key concepts.
An important part of this page is to be able to show the ratios in the simplest form. This process is similar to showing fractions in their simplest form, for example 6:4 can be simplified to 3:2 by dividing each by 2.
Remember, when finding the proportion of something the whole total of all items needs to be worked out. So to find what proportion of the total orders was tea, add up all the orders, which comes to 80. So the proportion of tea is 24/80. This can be simplified to 3/10.
