I can't figure out 6 - 2/3r = 1 1/2
The way we're learning how to solve it, is by using the LCD. the LCD I use is 6
The book says the answer is 6 3/4
But I keep getting the wrong answer.

  • Math -

    6 - 2/3r = 1 1/2

    -2/3r = 1 1/2 - 6
    -4/6r = -4 3/6
    r = -4 3/6 divided by -4/6
    r = -27/6 * -6/4
    r = 162/24 = 6 3/4
