Question 978235
Let
x = number of gallons
y = number of quarts


There are 4 quarts in a gallon. Think "quart" as in "quarter". So you will multiply the gallon amount by the factor "4 quarts/1 gallon". The "gallon" unit in the denominator will cancel with the original "gallon" unit.


This is what it will look like as an equation


{{{("x_gallons")*(("4_quarts")/("1_gallon")) = y}}}


{{{y = 4x}}}


So if you know the amount of gallons (x), you can use that equation to find the amount of quarts (y).
