Answer:
The answer is 399/500
Explanation:
When you start off, you look at the decimal to see what place the .798 is in. When you can see that is in the thousandths place, you just put 798 over 1000. Then you simplify this by dividing 798 and 1000 by 2. After checking to make sure the fraction can't be simplified anymore, your final answer would be 399/500.
