8/32 factor out the 8 8*1/8*4 you can eliminate the 8 as it is a factor in both numerator and denominator 1/4 ---------simplest form
No, while 6 is a factor of 12, it is not a factor of 8, so 6 cannot be used to simply 8/12.
8/24 factor out an 8 8*1/8*3 cancel 8's; top and bottom 1/3 simplest form
8/81 is already in simplest form. The only common factor between 8 & 81 is 1.
2 x 2 x 2 = 8
36
104/48 factor out a 8 8*13/8*6 as 8 appears in both numerator and denominator it can be eliminated 13/6 -------- simplest form
3/8 (common factor 66)
(d - 8)(d - 4)
784/1000 factor out an 8 8*98/8*125 now, as the 8's top an bottom are like factors they can be canceled 98/125 -----------simplest form
(d + 4)(d + 8)
assume that you mean 8r + 112 = 8(r+14)
