0.6875 = 11/16 To convert a decimal into a fraction, write the decimal divided by 1 (0.6875/1) and then move the decimal point all the way to the right of the decimal number to convert it into a whole number and add as many zeroes as there are numbers after the decimal to the number on the bottom: 0.6875/1 = 6875/10000, then simplify he fraction: 6875/10000 = 1375/2000 = 275/400 = 55/80 = 11/16 Alternately simply divide time spent(27.5) by total time (40) and get 27.5/40 then try to simplify. multiply by 2 you get 55/80 then divide by five 11/16
