Think of it this way: when you write a mixed number, the fraction is out of 100. If the denominator is 8, find 1/8 of 100 by doing 100 divided by 1/8. This gives you 12.5. The entire fraction is 2/8, so we need to multiply 12.5 by 2, since it's only 1/8. 12.5 x 2 gives us 25. In the decimal, this would be equal to .25. A is the only answer that represents the mixed number as a decimal correctly.
Answer: 11:12 PM. explanation: - 10% of 8 is 0.8. (10% is 0.1, and you multiply this by 8) - multiply 0.8 by 60 so you can get the number of minutes before midnight (this is 48). - 48 minutes before midnight is 11:12.
