Question

$9+\frac{3}{4}+7+\frac{2}{17}-(9+\frac{1}{15})=$?

• A. $7+\frac{719}{1020}$
• B. $9+\frac{817}{1020}$
• C. $9+\frac{719}{1020}$
• D. $7+\frac{817}{1020}$
• E. None of these

Answer 1

The correct option is D $7+\frac{817}{1020}$

Given the sum $=9+\frac{3}{4}+7+\frac{2}{17}-(9+\frac{1}{15})$
$=(9+7-9)+(\frac{3}{4}+\frac{2}{17}-\frac{1}{15})$
$=7+\frac{765+120-68}{1020}$
$=7+\frac{817}{1020}$
