Answer:
Sharon needs to make 7 trips
Step-by-step explanation:
13 1/2÷1 8/8
1 8/8 = 2 so Sharon can carry 2 gallons of water for each trip
2 can go into 13 6 times because 6x2=12 and that is the gcf
13 1/2- 12=1.5 or 1 1/2
to get to 13 1/2 sharon needs to make 1 more trip. Sharon can make 1 more trip because she can carry 2 gallons of water and there are 1 1/2 gallons left which is less than 2 so she can still make 1 more trip. In total Sharon will make 7 trips.
