A student changes 3/4 to a fraction with denominator 12. Which explanation is correct?
- Add 8 to both 3 and 4 to get 11/12.
- Multiply only 4 by 3 to get 3/12.
- Multiply 3 by 4 to get 12/12.
- Multiply both 3 and 4 by 3 to get 9/12.
Answer and explanation
Multiply both 3 and 4 by 3 to get 9/12.
Equivalent fractions name the same amount. Multiplying numerator and denominator by the same nonzero number preserves the value.
