Answer:
9 : 10
Step-by-step explanation:
First the ratio will be 63 : 70
Now, we have to simplify! The GCF (greatest common factor) is 7, so let's divide both numbers by 7 to maintain equality.
63/7 = 9
70/7 = 10
9 : 10 is the final answer!

Answer:
(7-4i)+(-2+5i) = 5 + i
Answer = 5 + i
Step-by-step explanation:
Group the real part and the imaginary part of the complex number
