Answer: a. 30
Step-by-step explanation:
First, make them have a common denominator
2/10 = 20/100

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 :)
