Answer:
C. Macy did not find the correct equivalent fraction with the denominator of 30
Step-by-step explanation:
4/5 and 19/30 common denominator is 30. Although Macy did calculate the correct denominator, she didn't calculate the correct numerator. Therefore, her equivalent fraction is incorrect. Macy should have multiplied both the numerator and the denominator of the fraction 4/5 by 6. The correct equivalent fraction is 24/30.
