Steps:
1. Change 1/11 to 2/22 by multiplying by 2
2. 9/22 + 2/22
3. 11/22
Then, to simplify it you divide by 11
4. Your answer is
1/2
You could subtract the denominator fro the numerator which would give you a total sum of 1 thousand an fifty five
Both are equal because the distance from AB is equal to RS.
To the nearest thousand, because when you are estimating numbers, you always round to the nearest higher place (like the nearest tenth if comparing 26 and 18).
