Answer:
It is closer to 1/2.
Explanation:
First of all, 10/9 is the same thing as 1 1/9.
Draw a number line:
1/2 1
--|------|------|------|-----|---|---|------|------|------|-----|-----
0/9 1/9 2/9 3/9 4/9 5/9 6/9 7/9 8/9 9/9
Halfway between 4/9 and 5/9 is the same as 1/2 and 9/9 is the same as 1.
You can see that 1/9 is way closer to 1/2 than 1.
So, 10/9 is closer to 1/2.
(There are other ways to solve this, but this way is easiest for me!)
