12/30 + 5/30 = 17/30
5/6
3/6 can be simplified to 1/2, and 1/2 is greater than 2/5. So, 3/6 is greater then 2/5.

12/30 + 5/30 = 17/30
Change 2/3 to 4/6. Add 1/6. Get 5/6.
2/5 + 5/6 you need like denominators to add fractions, 30 looks good; rationalize by multiplying by form of 1 6*2/6*5 + 5*5/5*6 12/30 + 25/30 = 37/30
3 and 3/8
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.
5/6 + 4/6= 9/6 which is also 1 1/2. You add 5+4 which would make it 9/6, 6 goes into 9 once leaving 3/6 which is 1/2, so 1 1/2.
5/6 - 2/6 = 3/6 = 1/2
5/6 x 12/5 = 2
5-2 1/6 = 2 5/6
2/3 + 5/6 = 4/6 + 5/6 = 9/6 =3/2
2/3+5/6=4/6+5/6=9/6=3/2
-20/6 + 5/6 = -15/6 = -5/2 or -2 and 1/2
