bulgar [2K]

Answer:

2\frac{1}{2} Cups

Step-by-step explanation:

First make 3 a fraction by throwing a one under it. Next multiple the two tops of the fractions together and then the two bottoms together:

\frac{5}{6} X\frac{3}{1}  = \frac{15}{6}

Next we convert to a mixed number:

2\frac{3}{6}

Finally, we simplify the fraction:

2\frac{1}{2}
