Answer:

3 $\frac{3}{4}$ yards of fabric

Step-by-step explanation:

In order to solve this problem, we should first make all of the fractions have common denominators. To do so we can turn the 1/2s into 2/4 which both equal 0.5 or 50%. Now we simply need to add together the pieces of quilt that she has and subtract that value from the total that she needs in order to calculate the amount of quilt that she is missing.

10 $\frac{2}{4}$ - (2 $\frac{2}{4}$ + 4 $\frac{1}{4}$ ) = x
