AMultiply top and bottom by the same number
BSubtract the denominator from the numerator
CAdd 1 to both the numerator and denominator
DSwap the numerator and the denominator
Answer & Solution
Correct answer: D. Swap the numerator and the denominator
1. A reciprocal is formed by inverting a fraction.
2. Inverting means swapping the top and bottom of the fraction.
3. The numerator moves to the denominator, and the denominator moves to the numerator.
4. Multiplying both parts by the same number, subtracting, or adding 1 all change the fraction's value instead of inverting it.
