is 7/8 >,< or = to 8/9?

  • math - ,

    First find the common denominator.

    7/8 and 8/9 = 63/72 and 64/72

  • math - ,

    here is a simple way to compare fractions
    Write them down side by side, leave a space between them.

    7/8 8/9

    crossmultiply
    first :top-left times bottom right
    second: bottom-left times top right
    so
    63 64
    what symbol between the 63 and 64 would make a true statement ?
    63 < 64
    put that same symbol between the original fractions.

    of course if you have a calculator, just change each fraction to a decimal, then it easy to decide which is the smaller
    7/8 = .875
    8/9 = .88888..

    since .875 < .8888.
    7/8 < 8/9
