1\2,4\9,4\18 find equivalent fractions with a common denominator and order from least to greatest

1\2,4\9,4\18
Here's one way to find the least common multiple or common denominator.
Write down the multiples of each of the denominators.
2, 4, 6, 8, 10, 12, 14, 16, 18, 20
9, 18, 27, 36
18, 36
Obviously, the common denominator is 18.
18/2 = 9; 1 * 9 = 9
1/2 = 9/18
4/9 = 8/18
4/18
I'm sure you can put them in order now. 
4/18, 8/18, 9/18
