For their craft project during the first week of camp, the campers used clothespins to make miniature rocking chairs. To make 90 chairs, they used 1,080 clothespins. How many clothespins did it take to make each chair?

Respuesta :

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

[tex]\frac{90 chairs}{1080 clothespins} =\frac{1 chair}{x clothespins}[/tex]

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.
