Ryan B's Sesame Street Video Post

Two Term Ratios

compares two quantities measured in the same units
ex. A:B, 9:18, 18 to 9

Three Term Ratios
compares the quantities measured in the same units
ex. A:B:C, 9:18:81, 81 to 18 to 9

- compares 2 quantities measured in different units

Unit Rates - a rate in which the second term is one
Unit Price - a unit rate used when shopping
ex. 3words/1h, $1/m


- A relationship that says two ratios or two rates are equal
- it can be written in fraction form
ex. use it to find cost of 15 donuts if 5 cost $0.10
5 / $0.10 = 15 / $x ; x = $o.30 ( multiply 5 by 3 and $o.10 by 3 )


  1. colorful post, but remember the difference between 0 (zero) and o as in ostrich.

  2. Great post Ryan, I liked that your post is neat and informative. I would prefer that you check some errors on the proportion example and a video would be nice.

  3. Nice post Ryan. It looks very organized but next time add your video. Other than that, great job.

  4. Colorful post, Ryan. It was also neat and organized but next time add your sesame street video. Other than that, good job.

  5. Good job, Ryan! I liked your post! It was colourful and accurate! Good job!
