36×(1/3-1/8) 7/8×3/49×8/9

36*(1/3-1/8)
=36*1/3-36*1/8
=12-9/2
=15/2
7/8*3/49*8/9
=7/8*8/9*3/49
=7/9*3/49
=1/21

36×(1/3-1/8) 7/8×3/49×8/9
=36x1/3 -36x1/8 =7/8x8/9x1/7x3/7
=12-9/2 =1/9x3/7
=7.5 =1/21

36x(1/3-1/8)
=36x(8/24-3/24)
=36x11/24
=66/4
=33/2

  1. =36*1/3-36*1/8

    =12-9/2

    =15/2=7you1/2

  2. 7/8*8/9*3/49

    =7/9*3/49=1/21

36×(1/3-1/8) 7/8×3/49×8/9
=36*1/3-36*1/8 =3/7*1/9
=12+4.5
=16.5 =1/21

36×﹙1/3-1/8﹚=36×1/3-36×1/8=12-36/8=60/8
