Dividing by a whole number is the same as multiplying by its reciprocal.<br><br>
&bull; \( \frac{5}{11} \div 10 = \frac{5}{11} \times \frac{1}{10} \)<br>
&bull; \( = \frac{5 \times 1}{11 \times 10} = \frac{5}{110} \)<br>
&bull; Simplify: HCF of 5 and 110 is 5. \( \frac{5}{110} = \frac{1}{22} \)<br><br>
Final Answer: A = 1, B = 22
