Answer:
-2/3
Step-by-step explanation:
Each mark on the number line is 1/3 unit.
Start at 1 2/3. That is the rightmost mark just before the right arrow.
You must subtract 2 1/3 units from it.
To subtract, you go left on the number line.
Every three marks you go left, you are subtracting 1 unit.
Go 3 marks to the left. That means subtracting 1 unit. Now you are at 2/3.
Now go another 3 marks to the left. You subtracted another unit. You are now at -1/3.
You still need to subtract 1/3, so go 1 more mark to the left. You arrive at -2/3. You have subtracted 2 1/3 from 1 2/3. The answer is -2/3.
