m, Mother's age

exact translation: 12=3%2B%281%2F4%29m
-
9=%281%2F4%29m
9=m%2F4
highlight%28m=36%29

Mother is 36 years-old.
The RUBBISH by JOS will never get you this answer. Beware!!
FYI: That person suggests that the mother is 12 years-old, the same age as her son. Now, isn't that the most RIDICULOUS thing? I hope you saw that!

Do it backwards. 12-3=9 9%2A4=36 Mother is 36 years old. Check, 1/4 of 36 is 9 and 3 more is 12. Correct.
