pogonyaev

Answer:

2.  92 ounces of Sprite

3.  1/6 do not want mustard on their ham sandwiches

4.  6 hours playing volleyball

5. 32 portions

Step-by-step explanation:

2.  Sam has 8 cans of Sprite.  Each can is 11 2/4 ounces

We can simplify 2/4 to 1/2

Multiply the number of cans by  the ounces per can

8 * 11  1/2

8 * 11.5

92 ounces

3.  1/2 of the students want ham.  1/3 of those do not want mustard

We multiply 1/2*1/3 = 1/6

1/6 of the students do not want mustard on their ham sandwiches

4.  8 hours at the beach.  3/4 of the time was spent playing volleyball

Multiply this together

8*3/4 = 8/4*3 = 2*3 = 6 hours

5.  We have 4 lbs of wings.  We divide it into 1/8 lbs parts

4 ÷ 1/8

Copy dot flip

4 * 8/1

32 portions
