Question

Mary spent 3/5 if her pocket money buying sweets 1/2bbuying fruits. What fraction of her pocket money did she spend

Answer 1

3/5 + 1/2 > 1
There is no way she could have spent more than she had.

Now, if she spent 3/5 on sweets (leaving 2/5)
and then 1/2 of what was left on fruits, then she spent 1/5 on fruits.
3/5 + 1/5 = 4/5
