According to my calculations the answer is 19.5 or 19.50 you can pick either one but your teacher will probably want the first.

[tex]1 \frac{3}{4} [/tex]  x 6  (or [tex] \frac{6}{1} [/tex]

Change 1 3/4 to an improper fraction = [tex] \frac{7}{4} [/tex]

[tex] \frac{7}{4} [/tex] x[tex] \frac{6}{1} [/tex] = [tex] \frac{42}{4} [/tex]  = 10 [tex] \frac{2}{4} [/tex] cups 
Reduce the answer and get 10 [tex] \frac{1}{2} [/tex] cups
