Question

Alex dyes dresses. He had to dye 30 dresses. He has so far finished 20 dresses. What fraction of dresses are still left ?

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

Answer 1

The correct option is C $\frac{1}{3}$

Total number of dresses Alex had to dye = 30.

Number of dresses he has finished = 20.
Number of dresses still left = 30 - 20 = 10.

The fraction of dresses still left $=\frac{10}{30}=\frac{1}{3}$.
