If you want to know what one sixteenth times two and one half means, you must understand rulers. Every eighth is divided into two sixteenths, for example, half of a seven-eighth inch is 7/16 inches, and one half of a four-eighth inch is 4/8 inches. The same goes for a fifth. You can find anything by multiplying numbers.
To calculate the fraction, you can use the fraction 1/2 to find the answer. This is equal to half of any amount, so you would divide one sixteenth by two. Similarly, one eighth of a seventeenth would be one-sixteenth. Half of a twenty-fourth would be twenty-sevenths times two. Once you’ve found the answer, you need to find the fraction that is one sixteenth times two and a half.
