-x/9=1/16
This is suppose to be solved using the multiplication principle. If possible please show me not just the answer but how you came up with it so I understand how to do these problems. Thank you

  • math 116 - ,

    multiply both sides by 144 (which is 9 x 16)

    (144)(-x/9)=(144)(1/16)
    16(-x) = 9(1)
    -16x = 9
    x = /9/16

    you could just 'cross-multiply' to get the same result faster:
    (-x)(16) = 1(9)
    x = -9/16

    In general find the lowest common denominator of your fractions, and multiply each term by that.
    This will guarantee that all your denominators will cancel, and your fractions will disappear.
