I need some help with this question :/

Answer 1

You have one of the answers correct. The fraction 4/8 is equal to 1/2

Other answers are: 5/10, 10/20, and 6/12

If you reduced each of those fractions, you'd get to 1/2. 

You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.

Answer 2

Answer: 1 / 2 , 5 / 10 , 10 / 20 , 6 / 12

Explanation: 4/8 can be simplified to 1/2. From this we can conclude that of the provided possible answers, those that can be simplified to 1/2 will be equivalent to 4/8.
