9 * 3 1/2=

Which choice is the most reasonable answer?

31.5 or 63/2

Step-by-step explanation:

to do this, first you need to transform the mixed number (3 1/2) into an improper fraction, to get 7/2.

then you just multiply 9 by 7/2

9/1 (7/2)

63/2 = 31.5

both of the answers in bold are correct
