You basically simplify for this one,18 / ? = 9
18/2=9

Answer:
i
Step-by-step explanation:
Why is i the square root of negative one?
The term "imaginary" is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero, which has one double square root.
You just convert 3/10 into 30/100 and add 30/100 + 4/100 which is equal to 34/100 and if you simplify it's equal to 17/50
