-370
They could be: 10 and -40 because 10-40 = -30 and 10 times -40 = -400
They are -40 and 10.
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.
To find 66 percent of a number, multiply the number by 0.66. In this instance, 0.66 x 400 = 264. Therefore, 66 percent of 400 is equal to 264.
Multiply by 20 and divide by 100 or alternatively, just multiply by 0.20. Example: 20% of 400 is 80.
Well, a square number is the answer to a number multiplied by itself. So, what you'd have to do is multiply 20*20, and the answer is 400.

3/400*100% first find what is 1/400 1/400 = 0.0025 and then multiply this by 3 3*1/400 = 3*0.0025 = 0.0075 then multiply this by 100% => 3 is 0.75% of 400
400*0.34 = 136 all you need to do to find a percent is divide the percentage by 100, and multiply this decimal number by the total. So here, I have divided 34 by 100 to give 0.34, and then multiplied this by our total of 400 to give 136.
475
400 - 225 = 175
To find 41 percent of a number, multiply the number by 0.41. In this instance, 0.41 x 400 = 164. Therefore, 41 percent of 400 is equal to 164.
To find 66 percent of a number, multiply the number by 0.66. In this instance, 0.66 x 400 = 264. Therefore, 66 percent of 400 is equal to 264.
To find 5 percent of a number, multiply the number by 0.05. In this instance 0.05 x 400 = 20. Therefore, 5 percent of 400 is equal to 20.
When a number is being squared you multiply the number by itself.Ex: 9squared = 9x9 =81Ex: 20squared =20x20 =400
Remember that "per cent" just means "out of 100". To find it out of 400, you simply need to multiply by 4.So 12.5 percent x 4 = 50.
Multiply by 20 and divide by 100 or alternatively, just multiply by 0.20. Example: 20% of 400 is 80.
Yes and to get it you multiply 20 times 20. 20x20=400
