Paulo's Sesame Street Video Post

Ratios
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

Rate
- 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

Proportion

- 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 )
