Answer 1

She will go for 7 trips if she has  15 1/2 gallons of water

Proportion and equations

From the given information, Ellen can carry 1 3/8 gallons of water each trip, this means:

• 1 trip = 11/8 gallons

In order to calculate the number of trips, it will take to make 15 1/2 gallons of water, we will have:

x = 21/2 gallons

Take the ratios of both expressions:

1/x =  11/8 * 2/21

1/x = 22/168

x = 168/22

x = 7.64 trips

Hence she will go for 7 trips if she has  15 1/2 gallons of water
