Question

Marvin has $\frac{9}{13}m$ of cloth out of which he uses $\frac{3}{13}m$ to cover a chair. Now, Marvin is left with cloth.

• A. $\frac{12}{13}m$
• B. $\frac{10}{13}m$
• C. $\frac{6}{13}m$
• D. $\frac{5}{13}m$

Answer 1

The correct option is C $\frac{6}{13}m$

Length of the cloth with Marvin = $\frac{9}{13}m$
Let's represent it on a fraction bar.

Cloth used to cover the chair = $\frac{3}{13}m$
Let's represent it on a fraction bar.

Let's calculate the cloth left with Marvin.


As the denominators of the fractions are same, the numerators can be subtracted directly and the denominator remains same.

$=\frac{9}{13}-\frac{3}{13}$ (like fractions)

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

$=\frac{6}{13}m$

Hence, $\frac{6}{13}m$ of cloth is left with Marvin.
