Answer: 3/10
Step-by-step explanation:
Since the rest of the trees are pears trees and plum trees in the ratio of 7:5 and there are 175 plum trees, the number of pear trees will be:
= 175 ÷ 5/7
= 175 × 7/5
= 245
Plum trees = 175
Pear trees = 245
Apple trees = 600 – (175 + 245)
= 600 – 420
= 180
Fraction of apple trees = Number of apple trees / Total number of trees
= 180/600
= 3/10
