The tens place is the bolded number below
67
When rounding you want everything after the tens place (after the bolded number) to be zero.
To determine if you round up or stay the same you must look at the number after the 6. In this case the number after the 6 is 7.
A number will round up if this number (7) is 5 or greater. If it is smaller then 5 then the decimal will not round up.
In this case 7 is larger then 5. This means that the 6 will round up to 7 and everything after it will become zeros...
