Answer: a. 30

Step-by-step explanation:

First, make them have a common denominator

2/10 = 20/100

Then you subtract

50/100 - 20/100

Which leaves you 30/100

So, your answer is A

Answer:

2/10 + 30/100 = 50/100

Step-by-step explanation:

First, you want to multiply 2/10 by 10, to get the same common denominator in both numbers, you would get 20/100. Then, its pretty simple from there, you just add the number that gets you to 50, which is 30, 20 + 30 =50. I Hope This Helps :)
