Question

In the woods there are 420 silver birch trees, 160 oak trees and 300 wood cherry trees what percentage of the trees are oak trees?

Answer 1

Find out the percentage of the trees are oak trees .

To prove

Formula

`Percentage = (Part\ value*100)/(Total\ value)`

As given

In the woods there are 420 silver birch trees, 160 oak trees and 300 wood cherry trees .

Total number of trees = 420 + 160 + 300

= 880

Part value = 160 oak trees

Put all in the formula

`Percentage = (160* 100)/(880)`

`Percentage = (16000)/(880)`

Percentage = 18.2 % (approx)

Therefore 18.2 % (approx) of the trees are oak trees .
