Question

Charles bought $\frac{2}{5}$ kg of salt from one shop and $\frac{1}{5}$ kg of salt from the other shop. How much salt did he buy in all (in kg)?

• A. $\frac{4}{5}$
• B. $\frac{3}{5}$
• C. $\frac{1}{5}$

Answer 1

The correct option is B $\frac{3}{5}$

Concept Used: To add like fractions, add numerators and put over the same denominator.

Salt bought from one shop $=\frac{2}{5}$ kg
Salt bought from the other shop $=\frac{1}{5}$ kg
Total quantity of salt $=\frac{2}{5}+\frac{1}{5}$
$=\frac{2+1}{5}$
$=\frac{3}{5}$ kg
So, Charles bought total $\frac{3}{5}$ kg of salt.
