Explanation:
Here is the full question :
n a managed forest, three different trees are planted. The trees are beech, holly and maple.
For every beech tree planted, there are 2 holly trees planted and 5 maple trees planted.
(a) Write down the ratio of trees.
b) If 40 maple trees were planted, how many beech trees would be planted? ​
the ratio of beech to holly to maple = 1 : 2 : 5
number of maple trees planted =( ratio of maple trees / sum of ratios ) x total number of trees
sum of ratios = 1 + 2 + 5 = 8
let a = total number of trees planted
( 5/8 ) x a = 40
a = 64
total number of beech planted = (1 / 8 ) x 64 = 8
