Answer:
a)
Step-by-step explanation:
There are several ways this can be accomplished. Students could survey every 20 students until they've asked 100 students, or they could ask 1 or 2 people at each cafeteria table during each lunch, just for examples.
2. 1/4 =2/8
5/8 =5/8
1 hour=8/8
The rule is to add 3/8 every time so the answer would be...
11/8= Thur
14/8 = 1 and 3/4 of hour.
4. 5 - (1, 1/2 + 1, 3/4) =
1/2 = 2/4
1, 2/4 + 1, 3/4 = 2, 5/4 = 3, 1/4
5 (4, 4/4) - 3, 1/4 = 1, 3/4
Glad to Help!
