Question

Vanesa bought $8\frac{5}{7}$m cloth for her dress. If the designer uses $4\frac{1}{3}$m for making the dress , the length of the remaining cloth is

• A. $6\frac{4}{7}$ m
• B. $2\frac{9}{11}$ m
• C. $4\frac{8}{21}$ m
• D. $13\frac{4}{7}$ m

Answer 1

The correct option is C $4\frac{8}{21}$ m

Here, Vanesa bought $8\frac{5}{7}$ m cloth for her dress. Designer uses $4\frac{1}{3}$ m for making the dress.

Length of the remaining cloth
= Total length of the cloth bought - Length of the cloth used
= $8\frac{5}{7}-4\frac{1}{3}$
= $\frac{61}{7}-\frac{13}{3}$
= $\frac{183-91}{21}$
= $\frac{92}{21}$
= $4\frac{8}{21}$
Hence, length of the remaining cloth will be $4\frac{8}{21}$ m.
