Answer:
7 1/2 (7.5)
Step-by-step explanation:
I solved it using conversions and regular math!
3 2/1 = 5 (convert to an improper fraction)
1 1/2 = 3/2 (convert to an improper fraction)
3/2 * 5 = 15/2 (multiply using numerator * numerator (3*5) and denominator * denominator (2*1))
15/2 = 7 1/2 (convert to a mixed number)
7/12 = 7.5 (convert to a decimal if needed)
