​Lesson 5 Summary

​All ratios that are equivalent to

a: b can be made by multiplying both a and b by the same number.

​

​For example, the example 18:12 is equivalent to 9:6 because both 9 and 6 are multiplied by the same number 2.

​3:2 is also equivalent to 9:6, because both 9 and 6 are multiplied by the same number. 1/3

Is 18 : 15 equivalent to 9 : 6?

​

​No, because 18 is 9 x 2, but 15 8 not 6 x 2.
