Question 1018962
.
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? 
---------------------------------------------------------------


<pre>
You have these two equations


T = {{{G/7}}} and T = {{{M/4}}},


where T is Tom's weight, G is grandfather's weight and M is mother's weight.

Hence, {{{G/7}}} = {{{M/4}}},

which implies M = {{{(4G)/7}}}.

<U>Answer</U>. Mother's weight is {{{4/7}}} of grandfather's weight.
