### Josell's Sesame Street Post

My group was made up of Melanie, Kristel, and Me.

Ratio

Two term ratio- compares two quantities measured in the same units.
ex. 2:3

Three term ratio- compares three quantities measured in the same units.
ex. 2:3:4

Part to part ratio- compares different parts of a group to another part of the same group.
ex. 4:2

This is a diagram
:

Rates:

ex. 2m/8hr

unit rate- a rate in which the second term is one.

Proportional Reasoning:
-Is a relationship that says that two ratios or two rates are equal.
example- 1/2 = 2/4

This was the video that Melanie, Kristel and I were planning to do.

1. Good job, Josell !
I liked your video.
Your picutres and examples were good.
I suggest next time you make the font bigger, so it's easier to read
