Answer:
The generator used 1 3/4 gallons of fuel each hour
Step-by-step explanation:
The generator runs for 2 1/2 hours and uses 4 3/8 gal of fuel during this time. This can be written as the ratio 2 1/2 hours : 4 3/8 gal
To find how much fuel is used in one hour, divide both sides by 2 1/2
2 1/2 divided by 2 1/2 = 1
4 3/8 divided by 2 1/2 = 35/8 divided by 5/2 = 35/8 x 2/5
35 x 2 = 70 and 8 x 5 = 40, which gives the answer 70/40
70/40 simplified is 7/4, which is 1 3/7 as a mixed number
The generator used 1 3/4 gallons of fuel each hour
