Question

Rasika bought some chocolates from the store and gave away $\frac{20}{35}$ fraction of the total to her sister. What fraction of chocolates are left with Rasika?

• A. $\frac{7}{3}$
• B. $\frac{3}{7}$
• C. $\frac{5}{7}$
• D. $\frac{4}{7}$

Answer 1

The correct option is B $\frac{3}{7}$

The fraction of chocolates given to her sister $=\frac{20}{35}$
On dividing numerator and denominator of $\frac{20}{35}$ by 5, we get,
$\frac{\frac{20}{5}}{\frac{35}{5}}=\frac{4}{7}$

$\therefore$ The fraction of chocolates left with Rasika $=1-\frac{4}{7}=\frac{7-4}{7}=\frac{3}{7}$
