null

Answer questions 4 - 6

In science class, Noah, Tyler, and Jada are building a model of a roller coaster out of 1-foot-long paper straws.

Noah needs a piece that is 7/12 foot long.
Tyler needs one that is 1/4 foot long
Jada needs one that is shorter than the other two.

Jada says, “We can just use one straw for all these pieces."

Draw a diagram to represent this situation and explain to your partner how it matches the situation.
Then, find the length of the piece of straw that could be Jada’s piece.
