Question

Mother is m years old, and she is four times as old as her daughter. How much older is the mother than her daughter?

Answer 1

(3/4)m

Explanation:

Let d represent the daughter's age. Then the problem statement tells us ...

m = 4d

Solving for d, we get ...

d = m/4

Then the difference in their ages is ...

m - d = m - (m/4) = (3/4)m . . . the difference in ages
