What is a ratio?

Back

A ratio is a comparison of two quantities that shows the relative size of one quantity to another.

Front

How can a ratio be expressed?

Back

A ratio can be expressed in three ways: as a fraction (e.g., 3/4), using a colon (e.g., 3:4), or with the word 'to' (e.g., 3 to 4).

Front

What is a part-to-part ratio?

Back

A part-to-part ratio compares two parts of a whole. For example, in a bag of 10 candies, if 4 are red and 6 are blue, the part-to-part ratio of red to blue is 4:6.

Front

What is a part-to-whole ratio?

Back

A part-to-whole ratio compares one part to the entire whole. For example, if there are 5 red M&Ms in a bag of 20, the part-to-whole ratio of red M&Ms is 5:20.

Front

Are the ratios 12:4 and 3:1 equivalent?

Back

Yes, the ratios 12:4 and 3:1 are equivalent because they simplify to the same value.

Front

Which of the following is NOT a way to write a ratio? 3=4, 3:4, 3/4, 3 to 4

Back

3=4 is NOT a way to write a ratio.

Front

What is an example of a real-life ratio?

Back

An example of a real-life ratio is 4 meatballs to 1 cup of sauce.

Front

What does it mean if two ratios are equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities, even if the numbers are different.

Front

How do you simplify a ratio?

Back

To simplify a ratio, divide both terms by their greatest common divisor (GCD). For example, to simplify 8:4, divide both by 4 to get 2:1.

Front

What is the ratio of red M&Ms to total M&Ms if there are 5 red M&Ms in a bag of 16?

Back

The ratio of red M&Ms to total M&Ms is 5:16.
