Question

Sum of $\frac{8}{4},\frac{9}{6},1\frac{3}{5}$ is

• A. $\frac{150}{30}$
• B. $5\frac{3}{30}$
• C. $5\frac{2}{30}$
• D. $5\frac{1}{30}$

Answer 1

The correct option is B $5\frac{3}{30}$

The sum of the fractions $\frac{8}{4},$ $\frac{9}{6}$ and $1\frac{3}{5}$ is

$\frac{8}{4}+\frac{9}{6}+1\frac{3}{5}$

Now, simplification of the mixed fraction $1\frac{3}{5}$ is $\frac{5\times 1+3}{5}$ $=\frac{8}{5}$

LCM of the denominators $4,6,5$ is $60$.

So, $\frac{8}{4}+\frac{9}{6}+1\frac{3}{5}$ $=\frac{8\times 15+9\times 10+8\times 12}{60}$ $=\frac{306}{60}$

After simplification it can also be written as $5\frac{3}{30}$
