Question

Mrs.robert is 3 times as old as her son. The sum of their ages is 48 years. How old was Mrs.robert when her son was born? Explain how you solve.

Answer 1

48÷3=16+48=64 which are not the correct answer
15x3=45+15=60 nada
14x3=42+14=56 nope
13x3=39+13=52 getting closer but still wrong
12x3=36+12=48 corrrect!
Mrs.Roberts was 36 years old when she had her son (let's say his name is Roberto)
