Frankfurter · Answer 1

1. Answer=2/3

21=total guests

7=guests with whistles

21-7=14

14=guests without whistles

14 out of 21 guests did not have whistles. 14/21

reduce by dividing both the numerator and the denominator by 7

14/21=2/3

2. Answer=Fruit

1/2 bought veggies

5/6 bought fruit

To find out which one is greater, divide the numerator by the denominator

1/2=0.5

5/6=0.833

5/6 is the greater fraction

3. Answer=9 1/10 buckets

each day 1bucket+3/10 of a bucket is eaten

1day=1 3/10buckets

to find out how many buckets get eaten in 7 days, multiply 7 by 1 3/10

7*1 3/10=9 1/10buckets

9 1/10 buckets were eaten in a week
