Question

A man spends 2/5 of his salary on food 3/10 on houe rent and electricity.What fraction of his money still left with him?

Answer 1

Hey there!
Fraction of money spent on food = 2/5
Fraction of money spent on electricity & rent = 3/10

Fraction of amount spent = 2/5 + 3/10 = 4/10 + 3/10 = 7/10

Fraction of amount left = 1 - 7/10 =3/10

Therefore, 3/10 fraction of total amount is left with him.
