I got these problems wrong in class. but, think i have the right answer now. Can you check?

1. Jim's mother made pizzas for his birthday. SHe sliced the pizzas into 50 slices. She served Jeff and his 7 guests the same number of slices and she ate the rest. How many pieces of pizza did Jim's mother eat?

Steps: take 50/8 = 6.25; then multiply 8 guests * 6 slices = 48; then subtract 50-48 = 2. So, Jeff's mom at 2 piece of pizza.

2. Mrs. Smith made coffee for 7 members of her bridge club. Her coffee maker makes 30 cups. If she and her club members drink equal amounts, how many cups of coffee will still be in the coffee maker when her guests leave?

Steps: take 30/7 = 4.28; then mulitply 7 members * 4 = 28; then subtract 30-28 = 2. SO there's 2 cups left.
