Jennifer visits the store to buy 1/9 of a yard of a blue fabric and 4/9 of a yard of green fabric to make new pillow covers for a doll house . how many more yards of green fabric did jennifer buy than blue fabric?

1/3 of a yard

Explanation:

Let's say she got 10 yards of green and 3 yards of blue. This means she got 7 more yards of green since 10-3 = 7. So we simply subtract the values. The same applies to the fractions.

Subtract the fractions. The denominators are the same, so we subtract the numerators while keeping the denominator the same.

4/9 - 1/9 = (4-1)/9 = 3/9

Now reduce 3/9 to get 1/3. You do this by dividing each part by the GCF 3.

So Jennifer got 1/3 of a yard more green compared to blue.

note that 1 yard = 3 feet. If you divide both sides by 3, then it turns into 1/3 yard = 1 foot. So she got exactly one foot more of green than blue. Since your teacher wants the answer in yards, it's best to keep it as 1/3 (even though saying "1 foot" is easier than saying "1/3 yard", at least in my opinion).
