1. four noncoplanar points
2. two intersecting lines

First well change 3 1/4 to an improper fraction

3 1/4 = 13/4

then we'll divide 3 into 13/4

when we divide fractions we flip the second one and then multiply them

3       4      12
--- ×   = ---
1      13      13

they each would get 12/13 of a candy strip

I hope I've helped!
