how do you solve these problems?
1.2x/3 + 1/3  x/8= 2/3
2. 3n + 9/10 + n/5= 2 3/10
3. 3k/4  28  2k/3 = 37

#1: Multiply both sides by a common denominator, in this case 24.
So you'll get
24* (2x/3 + 1/3  x/8) = 24* (2/3 )
16x + 8  3x = 16
13x = 8
x = 8/13
#2: Multiply both sides by 10
#3: Multiply both sides by 12. 
how do you do number 2. with a mixed number like multiply it by 10

2 3/10 = 23/10
