Maths: pie charts

A pie chart shows different types of tree in a forest. There are 720 trees altogether. There are 30 ash trees and 54 oak trees.

Write in its simplest form, the ratio of ash trees to oak trees in the forest.

Help pleaseeeeeee 🙂

The question is asking how many ash trees there are compared to the number of oak trees. If there was 1 ash tree and 2 oak trees, the ratio would be 1:2 (in words, 'one to two'). Also written as 1/2 (there are half as many ash trees to oak trees). In this case, there are 30 ash trees to 54 oak, a ratio of 30:54 (thirty to 54) or 30/54 (in it's simplest form)

The ratio 30 : 54 can be simplified further. Both numbers are in the 6 times table. There are 5 6s in 30 and there are 9 6s in 54 so the simplified ratio is 5:9
