The number in the third decimal place is bolded bellow:
0.117647059
To determine if you round up or stay the same you must look at the number after the 7. In this case the number after the 7 is 6.
A number will round up if this number (6) is 5 or greater. If it is smaller then 5 then the decimal will not round up.
In this case this means that the 7 will round up to 8...
0.118
Hope this helped!
