In the cafeteria 100 were put out for breakfast. At the end of breakfast,27 remained. A. What is the ratio ofbthe number of milk cartons taken to the total number of milk cartons?

1. The ratio of milk cartons taken to total milk cartons,

100 - 27 = 73 were taken

73/100 is the ratio of milk cartons taken to total milk cartons

2. The ratio of milk cartons remaining to milk cartons taken

27 / 73 is the ratio of milk cartons remaining to milk cartons taken

step-by-step explanation:

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.

hope this ! ^w^
