In a 1.75 liter bottle fit 1.8492 quarters.

Explanation:

The quarter is a unit of volume. It is equivalent to $\frac{1}{4}$ of a gallon :

1gallon=3.78541L

Where L is liter

⇒

$\frac{1}{4}gallon=1quarter=\frac{3.78541L}{4}$

To find how many quarters fit in a 1.75 L bottle we can write :

$\frac{\frac{3.78541L}{4}}{1quarter}=\frac{1.75L}{x}$

Solving for x :

$x=\frac{(1.75L).(1quarter)}{\frac{3.78541L}{4}}$

x=1.8492quarters
