Question

If you subtract $15\frac{5}{3}$ from $17\frac{3}{2}$, you will get

• A. $1\frac{5}{6}$
• B. $1\frac{6}{7}$
• C. $1\frac{8}{6}$
• D. $1\frac{7}{6}$

Answer 1

The correct option is A

$1\frac{5}{6}$

Let us first convert the mixed fractions $15\frac{5}{3}$ and $17\frac{3}{2}$ to improper fractions.
i.e., $15\frac{5}{3}=\frac{15\times 3+5}{3}=\frac{50}{3}$ and $17\frac{3}{2}=\frac{17\times 2+3}{3}=\frac{37}{2}$
Now, $17\frac{3}{2}-15\frac{5}{3}=\frac{37}{2}-\frac{50}{3}=\frac{111-100}{6}=\frac{11}{6}=1\frac{5}{6}$
