the numerical expression for
7/8-3/4(2-1/6)-2/3 is equal to
I made a common denominator of 24
21/24-1&+12/24+3/24-16/24
-15/24+3/24-16/24
-12/24-16/24
-28/24
both are divible by 2
-14/12 & divide both by 2 again to get
-7/6
Is this correct?
Thank you

  • math -

    7/8-3/4(2-1/6)-2/3
    = 7/8 - 3/2 + 1/8 - 2/3
    = 21/24 - 36/24 + 3/24 - 16/24
    = -28/24
    = -7/6

    You are correct !

    Notice you evaluated the bracket first, I used the distributive property.
    Of course we have to end up with the same result, since both methods are valid.
