ok so same thing for this one, the first thing you want to do is make 2 1/6 an improper fraction, which will be 13/6 Your equation will then look like this 1/2( 13/6 + 7/8) So your next step is to find a least common denominator, do you know how to do that?

idk

OpenStudy (hockeychick23):

ok well you want to find a number that every one of your denominators within the parentheses (6, 8) can go into, in this case it is 24, so you need to multiply 13/6 by 4 which will give you 52/24 and 7/8 by 3 which will give you 21/24. Next step is to plug these into the equation. 1/2(52/24+21/24) Now 52+21 is what?

OpenStudy (anonymous):

73?

OpenStudy (hockeychick23):

yes, so you get 1/2(73/24) so you know 73*1=73 so what does 24*2 equal?

OpenStudy (anonymous):

48

OpenStudy (hockeychick23):

correct, so you get 73/48 as your final answer or if you want it as a decimal its 3.04 and as a mixed number it is 1 25/48
