Answer:

A. LCM=72 B. GCF=7 C. 7(5+9)

Step-by-step explanation:

A. 8/2=4/2=2 9/3=3 Use the denominators to find the LCM. In this case, the LCM is 72.

B. 35/5=7 63/3=21/3=7 The GCF for these numbers is 7 because it is the only factor that they have in common.

C. 7 x 14=88 Since 5 and 9 don't have common factors, they work perfectly for this problem.
