35 percent is 3000. What's the remaining 65 percent?

This is a primary school math problem. It's very difficult
First of all, if the total 35% is 3000, then the total should be 3000 / 35% = 3000 / 0.35
The remaining 65% should be 65% of the total, right?
The complete formula should be:
(3000÷35%)×65%
