What is the ratio of parallelograms to triangles?

Create an equivalent ratio by building more sets with the above ratio.

Some equivalent ratios to 1:2 are 2:4, 3:6, and 4:8.

Some equivalent ratios to 3:4 are 6 to 8,

9 to 12, and 12 to 16.

How are the concepts of equivalent ratios and equivalent fractions similar?

In the diagram above, 2/5 of the counters in the top row are red; however, 4/10 of the counters are red, so 2/5 = 4/10.

Sue received 36 votes and John received 9 votes. Write as many equivalent ratios as you can to represent this information:

• 36 : 9 or 4:1 (Sue received 4 votes for every 1 vote for John)

• 9:36 or 1:4 (John received 1 vote for every4 votes for Sue)

• 36:45 or 4:5 (Sue received 4 votes for every5 votes cast)

• 9:45 or 1:5 (John received 1 vote for every5 votes cast)

A ratio shows a relationship between two amounts.The ratio 2:3 might represent 2 red circles compared to 3 blue triangles. One type of ratio is a fraction. This is a ratio where a part is compared to the whole. In the fraction 2/3 an object such as a circle is subdivided into 3 equal parts and 2 of these are shaded.

A ratio might also involve the comparison of two quantities or amounts that have different units. These ratios are called rates. For example, at the store, 2 oranges sell for $1.00. The rate is 2/ $1.00. How many oranges could you buy with $5.00?
