Question

Lucia is helping her grandmother make a quilt. They have 4 yards of fabric, which is equal to 144 inches. They need an additional 1 1/2 yards of fabric to finish the trim.

Answer 1

They need an additional 54 inches of fabric

Explanation:

This can be solved by using the unitary method.

Unitary method is that we find the measure of 1 unit and then mulitply it with the required number to get the actual measurement.

4 yards of fabric is equal to 144 inches

1 yard of fabric is equal to 144 inches/4= 36 inches

They need an additional 1 1/2 yards of fabric

So multiplying 1 1/2*36= 3/2*36= 3*36/2= 108/2= 54 inches

They need an additional 54 inches of fabric
