Question

\[16 - 2 \div 7 + 6 \times 2 = ?\]

Options

• 16

• 14

• \[27\frac{5}{7}\]

• none of these

Answer 1

\[27\frac{5}{7}\]

We have:
16 - 2 ÷ 7 + 6 × 2
= 16 - \[\left( \frac{2}{7} \right)\]  [Performing division]

= 16 - \[\left( \frac{2}{7} \right)\]  [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]
