Question

Mr. Conrad's pecan pie recipe calls for 1 3/4 cups of pecans. He plans to make 6 pies for his family reunion. How many cups of pecans will Mr. Conrad need

Answer 1

$1 \frac{3}{4}$  x 6  (or $\frac{6}{1}$

Change 1 3/4 to an improper fraction = $\frac{7}{4}$

$\frac{7}{4}$ x$\frac{6}{1}$ = $\frac{42}{4}$  = 10 $\frac{2}{4}$ cups 
Reduce the answer and get 10 $\frac{1}{2}$ cups

Answer 2

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.
