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
[tex]\frac{3.8}{3.8} L=\frac{1}{3.8}gal[/tex]
[tex]1 L=\frac{1}{3.8}gal[/tex]
now, we will multiply both sides by 22
[tex]22*1 L=22*\frac{1}{3.8}gal[/tex]
[tex]22L=5.78947 gal[/tex]
[tex]22L=5.8 gal[/tex]
so, option-b.............Answer
