Question

Andy is one fourth as old as his grandfather who is 76 years old write an equation to determine whether Andy is 19 or 22 years old

Answer 1

76÷4= ; x=19, you divide 76 by 4 because if he is 1/4 then it would be a group of one of the 4's, thus saying ehen you divide 76 by 4, it equals 19, so he is 19 years old, you could also do 19×4 and 22×4 to see which equals 76.
