Question

When you divide a whole number by a fraction with a numerator of 1, find 3 examples using this rule.

Answer 1

When you divide a whole number by a fraction with a numerator of 1, you can think of it as multiplying the whole number by the reciprocal of the fraction. Here are three examples: dividing 4 by 1/2 equals 8, dividing 7 by 1/3 equals 21, and dividing 10 by 1/4 equals 40.

Step-by-step explanation:

When you divide a whole number by a fraction with a numerator of 1, you can think of it as multiplying the whole number by the reciprocal of the fraction. Here are three examples:

1. Dividing 4 by 1/2 is the same as multiplying 4 by 2. So 4 ÷ 1/2 = 4 × 2 = 8.
2. Dividing 7 by 1/3 is the same as multiplying 7 by 3. So 7 ÷ 1/3 = 7 × 3 = 21.
3. Dividing 10 by 1/4 is the same as multiplying 10 by 4. So 10 ÷ 1/4 = 10 × 4 = 40.
