a recipe that serves 4 calls for 1 3/4 cups of tomato sauce. if jerry makes 2 1/2 time that amount, how many cups of tomato sauce will he need?

4 and 3/8 cups

Step-by-step explanation:

1 and 3/4 times 2 and 1/2

1 and 3/4 as a mixed number is 7/4 (4 x 1 = 4 + 3 = 7) (keep denominator)

2 and 1/2 as a mixed number is 5/2 (2 x 2 = 4 + 1 = 5) (keep denominator)

7/4 x 5/2 = 35/8

8 will go into 35 4 times. When you subtract 35-32, you have 3 left over and keep the denominator of 8. So, the answer is 4 and 3/8.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
