1. the pizza at kwame's party is cut to into eighths, kwame eats 3 slices and the rest of the family eats 18 slices. there's 3 s
lices left over, how many pizza's have been ordered? and how do you know? 2. hair scrunchies come in a packages of 5.
suppose you have 2 1/5 of these packages to share among 4 friends.
a) do you have enough scrunchies to give each friend 3 scrunchies? how do you know?
b) do you have enough scrunchies to give each friend 2? how do you know?
(you don't have to answer the 2 questions if they are too hard for you)
1. If kwame eats 3 slices and the family eats 18 slices thats a total of 21 slices. Each pizza is cut into eighths so there has to be 8 slices to each pizza. There are 3 slices left over for a total of 24 when the eaten slices are added to the left over slices. 24 divided by 8 is 3 pizzas.
When you a positive number from a negative number you can just add the numbers and make the sum negative. -23 - 7.2 is like -1(23 + 7.2). So the answer is -30.2, answer choice A.
