Question

$\text{A person has}\frac{9}{13}\text{L of soft drink.He drinks}$
$\frac{3}{13}\text{of it. What quantity of soft drink is left with him?}$

• A. $\frac{5}{13}\text{L}$
• B. $\frac{6}{13}\text{L}$
• C. $\frac{7}{13}\text{L}$
• D. $\frac{4}{13}\text{L}$

Answer 1

The correct option is B $\frac{6}{13}\text{L}$

$\text{Fraction of soft drink the person has}=\frac{9}{13}\text{L}$

$\text{Fraction of soft drink he drinks}=\$\frac{3}{13}\text{L}$

$\text{Fraction of soft drink left =}$
$\text{Fraction of soft drink he has - Fraction of soft drink he drinks}$
$=\frac{9}{13}-\frac{3}{13}$

$=\frac{9-3}{13}$

$=\frac{6}{13}$

$\therefore \text{The fraction of cold drink left with him}$ $is\frac{6}{13}\text{L.}$
