Answer: The correct option is (D) 0.75 of a yard.
Step-by-step explanation: Given that Miranda needs 3.5 yards of fabric to make a curtain for her dining room window and 2.25 yards of the same fabric to make a matching curtain for her kitchen window. She buys 6.5 yards of fabric.
We are to find the number of yards of fabric that she will left over.
The total quantity of fabric that Miranda needs is given by
[tex]3.5+2.25=5.75~\textup{yards}.[/tex]
Since she buys 6.5 yards of fabric, so the quantity of fabric that she left over will be
[tex]6.5-5.75=0.75~\textup{yard}.[/tex]
Thus, Miranda has left over 0.75 of a yard of the fabric.
Option (D) is CORRECT.
