Question
Abigail is 9 years old, and her brother Ron is a third of her age.
How old will her brother be when Abigail is 18 years old?
Solution
Abigail is currently 9 years old and her brother Ron is a third of her age, which means Ron is 3 years old.
If we want to find out how old Ron will be when Abigail is 18, we first need to determine how many years it will be until Abigail is 18.
Abigail will be 18 in 9 years (18 - 9 = 9).
Since Ron is currently 3 years old, in 9 years, he will be 12 years old (3 + 9 = 12).
So, when Abigail is 18 years old, her brother Ron will be 12 years old.
