Answer:
6.73
Step-by-step explanation:
6 (whole number) 8/11 is 6.7272 approximately 6.73 (3 s.f)
the 6 whole number gives the 6.
8/11 is 0 and using the whole long division method gives 0.7272...
cause when you add zero to 8 it becomes 80 and 11 goes into 80, 7 times giving 77.
subtracting 77 from 80 gives 3 adding 0 becomes 30 and 11 into 30 is 2 giving 22
I hope this helps
