It is so very simple and quick to get the answer, especially since, if you need it, you can use the calculator that comes with your computer. But since you are obviously not able to do so, the answer is 800.
2x10,000+8x1,000+8x100+3x10+1x1
6 = 100s or 6x102 3 = 10s or 3x101 8 = 1s or 8x100
64 = 100% 8 = X% X = 8x100 ÷ 64 X = 12.5%
It would be... (8x100)+(6/101)+(0/102)+(9/103)
take the number and multiply it by .8 like .8x100 (80 percent of 100) = 80
894 =800 + 90 + 48(100) + 9(10) + 4(1)(8x100) + (9x10) + (4x1)(8x102) + (9x101) + (4x100)
0.12 by 8 can be divided by multiplying both by 100 that is 0.12x100/8x100 is 12/800 and when simplified 3/200.
The answer is 200% multiply 2.0 by 100. Multiply any decimal by 100 to make it a percent. Ex: .8 as a percent .8X100=80%
800 + 10 + 8 + 0.8 + 0.01 + 0.005 or (8x100) + (1x10) + (8x1) + 8/10 + 1/100 + 5/1000
3861 =3000 + 800 + 60 + 13(1000) + 8(100) + 6(10) + 1(1)(3x1000) + (8x100) + (6x10) + (1x1)
802.06 = (8 x 100) + (0 x 10) + (2 x 1) + (0/10) + (6/100)
Two eighths, or one fourth, as a percent is 25%. You can calculate it by multiplying the decimal in this case 2/8 by 100. It would look like this 2/8x100=25.
