Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning. Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food. Ezra says that Annabelle did not feed the dog enough food. Annabelle says she gave him more than enough. Who is right? Explain how they can compare the fractions to figure out who is correct.

Ezra is correct. 2/3 = 8/12, 3/4 = 9/12. 8/12 is less than 9/12

Step-by-step explanation:

We can multiply the fractions (by multiplying both the top and bottom of a fraction, its value remains the same) by the opposite denominator. This gives us a least common denominator, so we can easily compaire the fractions.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
