Answer:
1 1/4
Step-by-step explanation:
okay so to make 1 blanket she needs 4 1/2 yards of wool
the goal here is to add the fractions then subtract from the 4 1/2 to see how much more she needs.
STEP 1:
turn the fractions into mixed numbers[tex]\frac{3}{2}\ \frac{9}{4}[/tex]
STEP 2:
next you have to find the least common multiple.(in this case 4) now we convert them(3x2 and 2x2)6/4 and since the second one is already 4 it stays as 9/4.
STEP 3: add 6/4 and 9/4= 15/4 then turn it into an improper fraction, 4 goes into 15 3 times with 1 left over so 3 1/4
STEP 4: subtract 4 1/2 and 3 1/4
once again convert to mixed numbers, subtract the numerators then change it back to an Improper fraction.
