Colton made fancy purple costume decorations for each of the 5 dancers in his year-end dance performance. He cut 1/2 of a yard of ribbon into equal pieces to make the decorations.
How long was each piece of ribbon?

0.1 or 1/10 yards

So we know that Colton cut 1⁄2 of a yard of ribbon into equal pieces to make the decorations so what we can do is take that 1⁄2 and divided by 5 because we know that there are 5 dancers at his year end dance performance.

1⁄2 in a decimal form is 0.5 so 0.5 divided by 5 equals 0.1 or 1/10.
