I GIVE 70 POINTS Chris bought 10.4 gallons of gasoline. There are approximately 3.8 liters in 1 gallon. Which measurement is closest to the number of liters of gasoline Chris bought?

Try and give a good explanation bc I have a test over proportions tomorrow.

Thanks!

We know there are about 3.8 liters in 1 gallon. if Chris bought 10.4 gallons, that’s 10.4 * 3.8 liters

10.4 * 3.8 = 39.52 liters

as a proportion, we can write it as
3.8/1 = x/10.4
(number of liters per number of gallons. there are 3.8 liters per gallon, but we don’t know how many liters in 10.4 gallons yet, thus the x)

then you cross multiply (multiply one sides denominator to with the other sides numerator twice and set them equal)to get
1x = 3.8*10.4

simplify
x = 39.52 liters

hope this helped!

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get
