Answer:
Option D
Explanation:
For this problem, we have to look at the answer choices and simply those fractions to their simplest form. Whichever one is equal to 4/5 is our answer choice.
Option A) 2/3 is already in its simplest form. This is incorrect.
Option B) 5/8 is already in its simplest form. This is incorrect
Option C) 10/12 can be simplified to 5/6. But, this isn't equal to 4/5, so this is incorrect.
Option D) 8/10 can be simplified to 4/5. This is equal to 4/5, so this is correct.
Option D is the correct answer.
Hope this helps! :)
