On solving  $\frac{21}{42} \times \frac{1}{8}$  we get , $\frac{1}{16}$ .

Step-by-step explanation:

To solve :  $\frac{21}{42} \div8$

Solution :

• To solve given expression we take reciprocal of $8$ by changing its sign from division to multiplication .
• We write  $\frac{21}{42} \div8$  as  $\frac{21}{42} \times \frac{1}{8}$ .
• To solve the above expression we will follow BODMAS rule.
• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.
• where,  

         $\begin{array}{l} \\B = brackets \\ \mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { Division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

• According to above rule we will solve .

        $\frac{21}{42} \times \frac{1}{8} \\\\= \frac{1}{2} \times \frac{1}{8} \\\\= \frac{1}{16}$ .
