Eduardo has 4 1/2 yards of rope light. He needs 6 2/3 for his ceiling. How many more yards does he need?

2 1/6

Step-by-step explanation:

Because the denominators are different, and there are whole numbers involved, then first make the fractions improper.

4 1/2 - > 9/2

6 2/3 - > 20/3

Next, make the denominators the same by multiplying each fraction by the denominator of the other.

9/2 * 3 = 27/6

20/3 * 2 = 40/6

Then you can subtract the numerators because the denominators are the same:

40/6-27/6 = 13/6

Then you can convert to a mixed fraction if need be.

2 and one sixth, make the denominator into the same factor
