Question

$16-2÷7+6\times 2=?$
(a) 16
(b) 14
(c) $27\frac{5}{7}$
(d) none of these

Answer 1

(c) $27\frac{5}{7}$
We have:
16 - 2 ÷ 7 + 6 × 2
= 16 - $\left(\frac{2}{7}\right)$ + 6 × 2 [Performing division]
= 16 - $\left(\frac{2}{7}\right)$ + 12 [Performing multiplication]
= 28 - $\left(\frac{2}{7}\right)$ [Performing addition]
= $\frac{28}{1}-\frac{2}{7}=\frac{\left(196-2\right)}{7}=\frac{194}{7}=27\frac{5}{7}$ [Performing subtraction]
