The name ‘quart’ sounds like quarter ##->1/4##

From this you can see the link between 4 quarts = 1 gallon ‘~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ##color(blue)(“Solving for quarts in 5 gallons”)##

##color(brown)(“showing every step”)##

Using ratios ##(“quarts”)/(“gallons”) -> (“4 quarts”)/(“1 gallon”)##

But we need 5 gallons.

Then ##4/1=(“quarts count”)/5##

Multiply both sides by 5

##4/1xx5=(“quarts count”)/5xx5##

Write as ##4xx5=”quarts count” xx5/5##

But ##5/5 = 1##

##4xx5=”quarts count” xx1##

##20=”quarts count”##
