Question

Convert 2 Liters to gallons. Use the fact that 1 gal.= 3.8L.

a. 22L= 3.2gal
b. 22L= 5.8gal
c. 22L= 8.4gal
d. 22L= 83.6gal

Answer 1

we know that

1 gal.= 3.8L

we can also write as

3.8L=1 gal

Firstly, we will find for 1L

so, we can divide both sides by 3.8

`(3.8)/(3.8) L=(1)/(3.8)gal`

`1 L=(1)/(3.8)gal`

now, we will multiply both sides by 22

`22*1 L=22*(1)/(3.8)gal`

`22L=5.78947 gal`

`22L=5.8 gal`

so, option-b.............Answer
