The mother is older than her daughter by
years
Step-by-step explanation:
Mother is m years old, and she is four times as old as her daughter.
we need to find how much older the mother is than her daughter
- Put the age of mother equal 4 times the age of daughter
- Find the age of daughter
- Subtract the age of daughter from the age of mother to find how much older the mother than her daughter
∵ The mother's age = m
∵ Her age is four times as old as her daughter
∴ m = 4 × daughter's age
- Divide both sides by 4
∴
= daughter's age
- Subtract the daughter's age from her mother's age
∵ The difference of their ages = m -
- Change 1 m to a fraction of denominator 4, then 1 m = ![\frac{4}{4}m](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B4%7Dm)
∴ The difference between their ages =
-
= ![\frac{3}{4}m](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Dm)
∴ The mother is older than her daughter by
years
