0.005 x 400 = 2
When you need to find a percent, just multiply your base number (in this case 400) by the percent divided by 100 (so 5/100 = .05). So, 400 x .05 = 20.

Well, 5% is the equivalent to .05, or 5 out of a hundred. So see how many hundreds are in 400 (400/100)...there are 4 hundreds in 400. Then multiply 4 times 5. Then subtract that number from 400 (because you asked how much is 5% OFF). Your answer is 380. You could also subtract 5 from 100 and multiply the difference by 400.
