What does a ratio compare?

A ratio compares two or more quantities or numbers.

List the three ways to write a ratio.

The three ways to write a ratio are using a colon, in fractional form, or using the word 'to'.

Why is order important when writing a ratio?

Order is important because it determines which quantity is being compared to which. Changing the order changes the ratio.

What is the difference between a part-to-part ratio and a part-to-whole ratio?

A part-to-part ratio compares one part of a group to another part of the same group, while a part-to-whole ratio compares one part of a group to the total amount in the group.
