-1 divided by -7/2? I tried this on my calculator and got a demical, my teacher want's it in fraction form though.

  • Math -

    -1 รท (-7/2)
    = -1 x (-2/7)
    = 2/7

  • Math -

    -1 / (-7/2) = -1 * -(2/7) = 2/7

  • Math -

    Dividing by a fraction is that same as multiplying by the inverse of that fraction.

    (-1)/(-7/2) = (-1)(-2/7) = 2/7

  • Math -

    Inverse means the recpitile right? so like if it was 15, it'd be 15/1 x (-3/4ths) which -3/4ths is actually 4/3s? so 15/1x4/3

  • Math -

    Inverse means the reciprocal.

    You only use the reciprocal when you divide.

    15 / (3/4) = 15/1 * (4/3)

    Ah, okay. Thank you.
