    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
