(1/5)x400 = 80
20x20=400 40x10=400 5x80=400 2x200=400 1x400=400
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.

-370
16% of 400= (convert 16% to .16) .16 of 400= (in math of means multiply) .16 x 400= 64 Or divide 400 by 100 and multiply by 16, either way u get 64
24
3200 To solve this, multiply 8 and 4 and you will get 32. Then, you can add the two zeroes from 400
1/5 = 0.20 in decimal
1/5 = 20%
Yes and to get it you multiply 20 times 20. 20x20=400
divide the number by the denominator of the fraction 100 / 5 = 20 1/5 of 100 = 20 20 * 5 = 100
400 times 100 is equal to 40,000. To calculate this, you multiply 400 by 100, which results in 40,000. Multiplication is a basic arithmetic operation where you add a number to itself a certain number of times, in this case, adding 400 to itself 100 times.

2 and 5. You will need to multiply 2 four times and 5 twice.
