#5 3/4 "cups"#

Flour needed to make dough #= 10 1/4 = ((10 × 4) + 1)/4 = 41/4 "cups"#

He have #= 4 1/2 "cups" = ((4 × 2) + 1)/2 "cups" = 9/2 "cups"#

He needs

#=> 41/4 "cups" - 9/2 "cups"#

#=> 41/4 "cups" - (9/2 "cups" × 2/2)#

#=> 41/4 "cups" - 18/4 "cups"#

#=> (41-18)/4 "cups" = 23/4 "cups" = 5 3/4 "cups"#
