You need whitespace around math operations.

You want to calculate (current / max ) * 100.  This can also be
written as (current / (max/100) ).  If max equals 2048000 then
max divided by 100 is 20480.  Current divided by 20480 gives the
percentage.

Prove:  If the current rate is at 50 percent then it is at 1024000.
1024000 / 20480 is 50.

You're using the default ifInOctets and ifOutOctets so your target
should be:  Target[test]: 6:public at router:::::2 / 20480
