Question

$1\frac{4}{7}+7\frac{1}{3}+3\frac{3}{5}=?$

• A. 21
• B. 8
• C. 25
• D. 13
• E. 30

Answer 1

The correct option is D 13

Here, it can also be written as
$1+\frac{4}{7}+7+\frac{1}{3}+3+\frac{3}{5}$
or $?=(1+7+3)+(\frac{4}{7}+\frac{1}{3}+\frac{3}{5})$
or $?=\left(11\right)+\left(\frac{60+35+63}{105}\right)$
or $?=11+\left(\frac{158}{105}\right)$
or $?=11+1.5$
or $?=12.5\approx 13$
