$5 \frac{3}{4} cups$ $5 3/4 "cups"$

Flour needed to make dough $= 10 \frac{1}{4} = \frac{(10 \times 4) + 1}{4} = \frac{41}{4} cups$ $= 10 1/4 = ((10 × 4) + 1)/4 = 41/4 "cups"$

He have $= 4 \frac{1}{2} cups = \frac{(4 \times 2) + 1}{2} cups = \frac{9}{2} cups$ $= 4 1/2 "cups" = ((4 × 2) + 1)/2 "cups" = 9/2 "cups"$

He needs

$\Rightarrow \frac{41}{4} cups - \frac{9}{2} cups$ $=> 41/4 "cups" - 9/2 "cups"$

$\Rightarrow \frac{41}{4} cups - (\frac{9}{2} cups \times \frac{2}{2})$ $=> 41/4 "cups" - (9/2 "cups" × 2/2)$

$\Rightarrow \frac{41}{4} cups - \frac{18}{4} cups$ $=> 41/4 "cups" - 18/4 "cups"$

$\Rightarrow \frac{41 - 18}{4} cups = \frac{23}{4} cups = 5 \frac{3}{4} cups$ $=> (41-18)/4 "cups" = 23/4 "cups" = 5 3/4 "cups"$
