She has 5 yd of blue fabric.
She needs 1/4 yd of blue fabric for a square.
We divide 5 yd by 1/4 yd to see the number of squares the blue fabric is enough for.
(5 yd)/(1/4 yd) = 5 * 4 = 20
The blue fabric is enough for 20 squares.
Now we do the same for the pink fabric.
She has 7 yd of pink fabric.
She needs 1/3 yd of pink fabric for a square.
We divide 7 yd by 1/3 yd to see the number of squares the pink fabric is enough for.
(7 yd)/(1/3 yd) = 7 * 3 = 21
The blue fabric is enough for 21 squares.
She has enough blue fabric for 20 squares and enough pink fabric for 21 squares.
She starts using the pieces of fabric.
Each square needs both colors.
She uses 20 pieces of blue fabric with 20 pieces of pink fabric to make 20 squares, and she has one piece of pink fabric left. She cannot make another square because she does not have a blue piece of fabric to go with it, and she needs both colors for each square.
Answer: 20 squares.
