Question : 39

Total: 73

Evaluate

\left( \frac{6}{0.32} \div \frac{2}{0.084} \right)^{-1}

correct to 1 decimal place.

Solution:

$\left( \frac{6}{0.32} \div \frac{2}{0.084} \right)^{-1}$

= $\left( \frac{600}{32} \div \frac{2000}{84} \right)^{-1}$

= $\left( \frac{600}{32} \times \frac{84}{2000} \right)^{-1}$

= $\left( \frac{63}{80} \right)^{-1}$

= $\frac{80}{63}$

= 1.3 (to 1 decimal place)
