The standard method to write any fraction is to write the numerator followed by a slash (/) followed by the denominator
→ three eights is 3/8
To improve the look, the numerator can be made superscript and the denominator made subscript.
However, Unicode includes three eighths as a character ⅜ which I type using [Alt Gr][<SHIFT>][5] on this Linux box.
fraction 3 8ths of 16 = 63/8 * 16 = 48/8 = 6
27/8
43/8
3/4
Divide the top of the fraction by the bottom. 3 ÷ 8 = 0.375
It would be 11 over 8.
3/8ths =0.375 = 37.5%
0.375 inches
3/5 is not equivalent
To convert a fraction with 8 as the denominator into one with 64 as the denominator, one needs to multiply the top and the bottom of the fraction by 8. As 3 is the numerator on the fraction 3/8 we need to multiply it by 8. This gives us 24. So 3/8 = (3/8 x 8/8) = 24/64 So, there are twentyfour 64ths in three 8ths
If given a measurement that lists tenths of inches such as 0.3 inches, place the number in a fraction over the denominator 10. In this case, 3/10. To convert to 8ths, multiply the numerator by 8 and divide by 10 to get 2.4/8ths of an inch.
1 and 3/8ths is the same as 8/8ths + 3/8ths. This is summed to 11/8ths. Half of that would be 11/16ths.
