Andi needs 5 1_2yards of fabric for a project. She has a piece that is 3 1_4yards at school and a piece that is 1 1_2yards at home. How much more fabric does she need?

The amount of fabric she needs is 3/4 yards

Step-by-step explanation:

To calculate the amount of fabric needed, we need to subtract the sum of what she has at school and at home from what she needs.

What she has can be calculated by adding 3 1/4 + 1 1/2

This would be easier in terms of decimals.

3 1/4 = 3.25 (1/4 = 0.25)

while 1 1/2 = 1.5 (1/2 = 0.5)

Adding both, we have 3.25 + 1.5 = 4.75 yards

What is needed is 5 1/2 yards = 5.5 yards

What is needed more is thus 5.5 yards - 4.75 yards = 0.75 yards

Mathematically 0.75 in decimals = 3/4 in fraction form
