Well, darling, to write 1 over 400 as a percent, you simply multiply 1 by 100 and then divide by 400. That gives you a whopping 0.25%. So, there you have it, 1 over 400 as a percent is 0.25%.
0.25% = 1/400
400 percent = 4.0 or 4/1
1 400 000
1 million = 1,000,000 → 4 hundred million = 400 × 1 million = 400 × 1,000,000 = 400,000,000
400 = 202
