Posted by es on .
the numerical expression for
7/83/4(21/6)2/3 is equal to
I made a common denominator of 24
21/241&+12/24+3/2416/24
15/24+3/2416/24
12/2416/24
28/24
both are divible by 2
14/12 & divide both by 2 again to get
7/6
Is this correct?
Thank you

Reiny,
7/83/4(21/6)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.
