Step-by-step explanation:
1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.
We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.
x is the number of clothes pins for 1 chair
![\frac{90 chairs}{1080 clothespins} =\frac{1 chair}{x clothespins}](https://tex.z-dn.net/?f=%5Cfrac%7B90%20chairs%7D%7B1080%20clothespins%7D%20%3D%5Cfrac%7B1%20chair%7D%7Bx%20clothespins%7D)
Cross multiply to get
90*x= 1080*1
Divide both sides by 90 to isolate x
x = 12 clothespins
It takes 12 clothespins to make 1 chair.
