Answer:
a. 3.9714285714 b.1.404040404
Step-by-step explanation:
13.9/3.5
13.9/9.9
I do not know if this is correct, but give it a try.
To get 1 you need to multiply -3/8 by -2/2/3 or -2.67
You make them to improper fractions then you find a greatest common factor and then go from there
I'm pretty sure it's just 2,420.
