Question

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

Answer 1

The total is 100 cartons.

So, if there are 27 remained, that's means that 73 milk cartons were taken (100 - 27 = 73).

The ratio is
`(73 (number of milk cartons taken))/(100 (total))`

or 73%
