Mindy divides a rectangle or piece of fabric into eight equal size pieces for two sewing projects for project ac will use 1/2 of the fabric for project be she will use 1/4 of the original fabric john model to show how the fabric was divided and which pieces will be used with a unit fraction represents one of the pieces write the equation to find how much of the fabric will not be used f represent a fraction of leftover fabric

To represent this in a picture, you would draw a rectangle and break it into 8 equal sized pieces.

For project AC, 4 out of those 8 pieces with be used (4/8 = 1/2).

For project BE, 2 out of the 8 pieces will be used (2/8 = 1/4).

You can label 4 of them AC and 2 of them BE.

To represent what is remaining you would write the following math equation.

1 - 1/2 - 1/4 = f
8/8 - 4/8 - 2/8 = f
2/8 = f
1/4 = f

1/4 of the original fabric remains after these two projects.
