Answer 1

The answer for friday and saturday is 44.65 liters

Answer 2

Answer:

Dan bought 44.65 liters of gas.

Step-by-step explanation:

The gas Dan bought on Friday and Saturday in gallons is

$5\frac{1}{4}+6\frac{1}{2}$

$=\frac{21}{4} +\frac{13}{2}$

We collect LCM for the denominators,

$=\frac{21+26}{4}$

$=\frac{47}{4}$gallons

We now convert to liters using the relation,

$1\:gallon=3.8\: liters$

Let $\frac{47}{4}\:gallons=x\:liters$

Then,

$x=3.8\times \frac{47}{4}$

$x=\frac{38}{10}\times \frac{47}{4}$

$x=\frac{19}{5}\times \frac{47}{4}$

$x=\frac{893}{20}=44.65$

Therefore Dan bought 44.65 liters of gas.
