Answer 1

9 quilts
15+12=27
27 divide 3=9

Answer 2

Answer: We need 5 yards green felt and 4 yards blue felt for each quilt.

Explanation:

Let length of green felt be 'x' , length of blue felt be 'y' and and number of quilts be z.

If Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts.

⇒
`15x+12y=3z`

Now, divide both sides by 3 , we get

`5x+4y=1z`

Therefore, we need 5 yards green felt and 4 yards blue felt for each quilt.
