Answer:
B
Step-by-step explanation:
When you are subtracting a negative, it is the same as just adding a positive.
[tex]-9\frac{2}{7} + 10\frac{3}{7}[/tex]
We can rearrange the problem to read:
[tex]10\frac{3}{7} -9\frac{2}{7}[/tex]
Now, we can subtract the numbers and fractions separately.
[tex]10+\frac{3}{7} -(9+\frac{2}{7})[/tex]
[tex](10-9)+(\frac{3}{7}-\frac{2}{7} )=1+\frac{1}{7}=1\frac{1}{7}[/tex]
This is B
