Final answer:
The given problems involve division of fractions. For each problem, we convert the division to multiplication by using the reciprocal of the second fraction.
Step-by-step explanation:
In mathematics, when dividing fractions, you can use 'division by reciprocal' method. Here, you essentially multiply the first fraction by the reciprocal of the second fraction.
- Question a) 36/40 ÷ 4/5: Convert the division to multiplication by using the reciprocal of the second fraction. So, the question becomes 36/40 * 5/4 = 1.8
- Question b) 16/37 ÷ 3/37: This is a special case, because the denominators are the same. The division becomes 16/3 or approximately 5.333.
- Question c) 16/135 ÷ 72/265: Write the division as multiplication by multiplying 16/135 by reciprocal of 72/265, which results in approximately 0.178 or 17.8%.
