$2$ cups of detergent

This is a simple ratio question.

If $1/4$ cup of detergent is needed for $1/2$ load of clothes, we can write this for $4$ loads:

$(4 "load of clothes")*((1/4 "cup of detergent")/(1/2 "load of clothes"))$

$(4 cancel("load of clothes"))*((1/4 "cup of detergent")/(1/2 cancel("load of clothes")))$

$(4)*((1/4)/(1/2)) "cup of detergent"$

$2$ cups of detergent

1/4 1/4 cup of detergent is recommended for 1/21/2 load of clothes. How many is needed for 4 loads?
