Answer:
We need 5 yards green felt and 4 yards blue felt for each quilt.
<em>Step</em><em>-</em><em>wise</em><em>:</em>
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=3z15x+12y=3z
Now, divide both sides by 3 , we get
5x+4y=1z5x+4y=1z
<em><u>Therefore, we need 5 yards green felt and 4 yards blue felt for each quilt</u></em>.
