In your notebook, answer the following questions:
1) There are 12 eggs in 1 carton. In the delivery truck, 4 and 5/12 cartons of eggs break. In the store, a total of 2 and 9/12 cartons break. How many more cartons of eggs break in the truck than in the store?
2) Justin subtracts 5 and 1/3 from 10 and 2/3 by setting up the following subtraction sentence: "10 2/3 - 5 1/3= 5 1/3". Is Justin's difference correct? Justify your answer using drawings, words or numbers.
3) Mariah needs to add 4 and 10/100 and 3 and 20/100. She starts by using a denominator of 10 to write equivalent fractions for 10/100 and 20/100. Then, she adds the mixed numbers. Can Mariah have a correct sum with this method? Justify your answer using drawings, words, or numbers.
