Question

Subtract $15\frac{3}{5}$ from $17\frac{2}{3}$

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

We shall first convert the mixed fractions to improper fractions, as follows:

$15\frac{3}{5}$ = $\frac{15\times 5+3}{5}$ = $\frac{78}{5}$

$17\frac{2}{3}$ = $\frac{17\times 3+2}{3}$ = $\frac{53}{3}$

So, $17\frac{2}{3}$ - $15\frac{3}{5}$ = $\frac{78}{5}-\frac{53}{3}=\frac{234-264}{15}=-\frac{30}{15}=-2$
