Answer:
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

Given:
A diagram of two triangles.
To find:
Whether the triangles are congruent or not.
Solution:
In triangles DEF and DGF,
(Given)
(Reflexive property)
(Given)
Two corresponding angles and their included angles are congruent, so the triangles are congruent by ASA postulate.
(ASA congruence postulate)
Therefore, yes the triangles are congruent by ASA. Hence the correct option is A.
