Two Term Ratios
Compares two quantities measured in the same units.
Example: A:B 10:20 10 to 20
Three Team Ratios
compares three quantities measured in the same units.
Example: A:B:C 10:20:30 10 to 20 to 30
Compares two quantities measured in different units.
A rate in which the second term is one.
A unit rate used when shopping.
Example: $10/ 3 chocolate bars.
A relationship that says two ratios or two rates are equal.
Example: use it to find cost of 15 donuts if 5 cost $0.10
5/$0.10 = 15 / $x ; x = $0.30 (multiply 5 by 3 and $0.10 by 3)
