Problema Solution
Tom’s weight is 1/7th of his grandfather and 1/4th of his mother.
What fraction is Tom’s mother’s weight of his grandfather?
Answer provided by our tutors
Let 'x' represent Tom's mother weight and 'y' Tom's grandfather weight.
Tom's weight is 1/7 of his grandfather's weight or (1/7)y.
Tom's weight is 1/4 of his mother's weight or (1/4)x.
(1/4)x = (1/7)y multiply both sides by 4
x = (4/7)y
Tom's mothers weight is (4/7) of his grandfathers weight.
