work help: Math problem plz help ! - Help.com

i heard you can find math problems on ask.com
i know very little about math

well there can be 12 1 hour shifts or 6 2 hour shifts there is alot of them

you want to have a whole number as duration, therefore, 1hr, 2, 3, to 24.

you have the help of knowing the shifts are of equal length

thus, you can have:
24 div 1 = 24 1hr shifts
24 div 2 = 12 2hr shifts
24 div 3 = 8 3hr shifts
24 div 4 = 6 4hr shifts
24 div 5 = 4.8 5hr shifts (thus this is not acceptable)
24 div 6 = 4 6hr shifts
24 div 7 = not acceptable
24 div 8 = 3 8hr shifts
24 div 9 = not acceptable
24 div 10 = not acceptable
24 div 11 = not acceptable
24 div 12 = 2 12hr shifts
then from 13 to 23, they are all not acceptable
then
24 div 24 = 1 24hr shift

thus, you can do that in 8 ways, which you can get from the info provided
