Use the value of the ratio to determine which ratios are equivalent to 7: 15.

a. 21: 45

b. 14: 45

c. 3: 5

d. 63: 135

a. 21: 45

d. 63: 135

Step-by-step explanation:

Ratio or Relationship of two quantities is the result of comparing two quantities.

Such a comparison could be indicated as a reason, in four different ways, in this way:

1) a: b

2) a : b

3) a/b

d) The reason for a is a b.

Equivalent ratios can be used to show the same relationship between two quantities. Remember that the word "equivalent" means the same.

Problem development

We observe what are the equivalent relationships 7:15 and conclude that they are the following:

a. To find the equivalent ratio, we divide the numerator and denominator by the same number, In this case we divide by 3:

21: 45 = 21/45 = 21:3 / 45:3 = 7/15

d. To find the equivalent ratio, we divide the numerator and denominator by the same number, In this case we divide by 9:

63: 135 = 63/135 = 63:9 / 135:9 = 7/15
