Derec'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. Great post Derec, I liked the color but you look for errors.It would also be better if you have added a video.

  2. Nice post Derec. It looks very organized and it explains the words well. Next time add you video. Other than that, great job.

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

  4. Good job, Derec! I liked all the different colours. A tip is to look over your work before you post.
