to compare fractions, you need to get both fractions to have the same denominator.
The denominators are 3 and 6. Both 3 and 6 can be multiplied by something to get 6.
6 x 1 = 6 and 3 x 2 = 6
First, we'll start with 5/6 to show how this works.
we are going to multiply 5/6 by 1/1
5 x 1 = 5
6 1 6
Next, we'll change 2/3 to a denominator of 6.
we are going to multiply 2/3 by 2/2
2 x 2 = 4
3 2 6
Finally we can compare both fractions because they both have the same denominator.
5/6 > 4/6
so
5/6 is greater than 2/3
