A: 4/9, 2/3
B: 6/15, 9/12
C: 12/16, 15/20
D:18/20, 24/30


explain how o do it plsss

  • math -

    (C) 3/4

  • math -

    I will do one for you

    B:

    if 6/15 = 9/12 then 6(12) = 15(9), which is FALSE

    or you can reduce each to lowest form
    6/15 = 3/5
    9/12 = 3/4 , obviously not the same

    do the others the same way
