two-term ratio:
A term used to refer to ratio that compares two quantities of the same unit to each other.

For example,

4:3

would be a two-term ratio.


three-term ratio:
A term used to refer to ratio that compares three quantities of the same unit to each other.

For example,

1:2:3

would be a two-term ratio.


part-to-part ratio:
A term used to refer to ratio that compares two different parts of the same ratio to each other.

For example,

3:7

would be a part-part ratio.


part-to-whole ratio:
A term used to refer to ratio that compares all of the different parts of the same ratio to each other.

For example,

3 : 7 : 10 : 5

would be a part-to-whole ratio.


unit rate:
A rate with any numerator but with a denominator of one.

For example,

70 9052935235
--- or -----------------
1 1


unit price:
The price of a single or one unit in a group or pack of the item.

For example,

If $1.00 was for 5 apples, then the unit price would be $0.20 for each unit or apple.


proportion:
A special type of ratio expressing a relationship between the part and the whole where the numerator is always part of the total and the denominator is the total.

For example,

There are 32 boys in a school of 60 school kids

or

32
---
60


would be proportion.
