Question

John decided to cook since he was feeling hungry. He found that only $\frac{1}{3}$rd litre of milk was left in the kitchen. So, he bought $\frac{1}{2}$ litre of milk. Find the total amount of milk he has.

• A. 4/9 litre
• B. 4/5 litre
• C. 5/6 litre
• D. 1/9 litre

Answer 1

The correct option is C

5/6 litre

To know the total amount of milk john had, first we need to add the quantity of milk.
Steps involved in addition of fractions are:
1.Retain the common denominator
2.Then, add numerator
Multiply both numerator and denominator of numbers with the product of the denominators of the numbers which is 6 since $2\times 3=6$.
So, $\frac{1}{3}$ + $\frac{1}{2}=$ $\frac{2+3}{6}=$ $\frac{5}{6}litres.$
