Answer:

A. 5

Explanation:

let us use the part to whole approach

given the ratio= 2:9

the total ratio= 2+9=11

the total trees planted=27

using the part to whole, the oak trees planted is given as

let the number of oak trees be x

2/11=x/27

cross multiply we have

11x=27x2

11x=54

x=54/11

x= 4.90

approximately 5 tree
