Question

In a cafeteria 1/10 of the students are eating salads, and, 2/5 are eating sandwiches. there are 20 students in the cafeteria. how many students are eating lunches other than salads or sandwiches

Answer 1

20 x 1/10 have salads = 2 students

and

20 x 2/5 have sandwiches = 8 students

so 10 students are eating lunches other than salads or sandwiches

(20 - 2 - 8)

or 1/10 + 2/5 = 1/10 + 4/10 = 5/10 have salad and sandwich

so 5/10 have no salad no sandwich

and 5/10 x 20 = 10

Answer 2

5/10, or 1/2

Explanation:

2/5 = 4/10

4/10 + 1/10 = 5/10

10/10 - 5/10 = 5/10

Simplified, 1/2
