Nikki has 3 pieces of yarn. 5/6 ft long, 5/3 ft long, 3/2 ft long arrange from shortest to longest. draw a number line model

TO compare these fractions you would have to find the lcm first of 6,3 and 2
The lcm is 6
Next, you would have to multiply all fractions by a number so the denominator is 6
5/6 is already good 
5/3 times 2 = 10/6
3/2 times 3 =9/6
The new fractions are 5/6    10/6       and      9/6
In shortest to longest, the answer is 5/6   9/6      10/6
