The question

How old is the beech tree?

The elm tree has stood 5 times as long as the beech tree, and the two together are 150 years old.
5 + 1 = 6
5 + 1 = 6
150 ÷ 6 = 25 years
asked:How old is the beech tree?
25 years
  1. Read it through. One is a multiple of the other, so think in equal parts: the smaller is one part, the bigger is several.
  2. Added together they are all the parts at once: 5 + 1 = 6 parts in total.
  3. One part is the smaller age, so divide by the 6 parts: 150 ÷ 6 = 25 years.
  4. Answer the question that was asked — "How old is the beech tree?" — 25 years.
