Question

Dan bought 5 1/4 gallons of gas on Friday and ​ 6 1/2 ​ gallons of gas on Saturday. How many liters of gas did he buy? Assume 1 gallon = 3.8 liters.

Answer 1

the answer for friday and saturday is 44.65 liters

Answer 2

Dan bought 44.65 liters of gas.

Explanation:

The gas Dan bought on Friday and Saturday in gallons is

`5(1)/(4)+6(1)/(2)`

`=(21)/(4) +(13)/(2)`

We collect LCM for the denominators,

`=(21+26)/(4)`

`=(47)/(4)`gallons

We now convert to liters using the relation,

`1\:gallon=3.8\: liters`

Let
`(47)/(4)\:gallons=x\:liters`

Then,

`x=3.8* (47)/(4)`

`x=(38)/(10)* (47)/(4)`

`x=(19)/(5)* (47)/(4)`

`x=(893)/(20)=44.65`

Therefore Dan bought 44.65 liters of gas.
