Answer:
a
Step-by-step explanation:
8x^8=2*2*2*x*x*x*x*x*x*x*x
28x^4=2*2*7*x*x*x*x
GCF is the common group
GCF=2*2*x*x*x*x
GCF=4x^4
24/16 are both multiples of 8
24/8 = 3 16/8 = 2
3/2
Lets change "16" by its to 16/1 .. since nothing can't help support 16 by itself when it is going into 7/10
Now that we change that ... your problem becomes 7/10 × 16/1
7/10 × 16/1 = 11 1/5
Because
7(16) / 10(1) = 112/10
Now lets go. to how we solve the for the answer
112/10 = 11 1/5
