Question 58

$$\frac{1}{12} \div \frac{1}{12} \div \frac{1}{12} \div \frac{1}{12} \div \frac{1}{12}$$ = ?

Solution

Expression : $$\frac{1}{12} \div \frac{1}{12} \div \frac{1}{12} \div \frac{1}{12} \div \frac{1}{12}$$

= $$[\frac{1}{12} \div \frac{1}{12}] \div [\frac{1}{12} \div \frac{1}{12} \div \frac{1}{12}]$$

= $$(1 \div \frac{1}{12}) \div \frac{1}{12} \div \frac{1}{12}$$

= $$(12\div\frac{1}{12})\div\frac{1}{12}$$

= $$12\times12\div\frac{1}{12}$$

= $$144\times12=1728$$
