simplify 5 1/3 + (-3 9/18)
Dr. @Hero to the OR, please :-)
We did one yesterday, see here: http://openstudy.com/study#/updates/50f0c97ee4b0abb3d86f6c71
you can change 5 1/3 to somthing/6 and you can change -3 9/18 to something/6, then you subtract the fractions
change 1/3 to ?/6 => (2*1)/(2*3) => 2/6. Now 6/6 is the same as 1, so if you have 5 (ones) you have (5*6)/6 = 30/6, so 5 1/3 = 32/6, now do the same for -3 9/18
11/6 or 1 5/6 is the answer
