Hi!
First let's find the LCD of all of the fractions, and change all of them.
The LCD of 3, 6, 8, and 10 is 120.
Now change all of the fractions.
120/3 = 40
2 x 40 = 80
80/120
120/6 = 20
7 x 20 = 140
140/120
120/8 = 15
1 x 15 = 15
15/120
120/10 = 12
9 x 12 = 108
108/120
Now, line up all of the new fractions, and put them in order from least to greatest.
80/120, 140/120, 15/120, 108/120
15/120, 80/120, 108/120, 140/120
1/8, 2/3, 9/10, 7/6
^the answer
Hope this helps! :)
