BartSMP [9]

So she has used two kinds of sugar, brown and powdered.

She used $2 \frac{3}{4}$ cups of brown sugar and $1 \frac{3}{4}$ cups of powdered sugar: we need to add the two numbers:

$2 \frac{3}{4}$ + $1 \frac{3}{4}$ = 2+1+ $\frac{3}{4}+ \frac{3}{4}$ =3 $\frac{6}{4}=3+1+ \frac{2}{4} =4 \frac{2}{4}=4 \frac{1}{2}=4.5$

so the correct answer is 4.5
