B because when you round 1 and 7/9= 2 and 6 and 2/11= 6, and 2-6= negative 4. Answer: B.

7/9 is approximately 0.78 2/11 is approximately 0.18 So do we round up or down with 7/9?

Yep, So 1 7/9 rounds to 2.
What about 2/11?
OpenStudy (anonymous):
down ?
OpenStudy (anonymous):
0 ??
OpenStudy (anonymous):
Wait is it 6?
OpenStudy (samanthagreer):
0.18 If the number after the decimal place is 5 or more, we round up. If it is 4 or less we round down. So do we round up or down?

What's the number after the decimal place(period) 0.18
OpenStudy (anonymous):
18
OpenStudy (samanthagreer):
no 1 and is that 5 or more or is it 4 or less?
OpenStudy (anonymous):
4 or less
OpenStudy (samanthagreer):
Yes, so we round down to 0. So -6 2/11 rounds down to -6. Now subtract 2 - 6
