Answer:
Always.
Step-by-step explanation:
Rational numbers are numbers that can be written as a fraction OR a decimal
Option C is needed because the reason for proving this pair of congruent triangles is SAS, (an angle between 2 equal sides)
First, change the mixed fraction into improper fraction
1 1/7 = 7/7 + 1/7 = 8/7
(4/7)/(8/7)
To solve, flip the second fraction, and change the division into multiplication
(4/7)/(8/7) = (4/7) x (7/8)
Multiply, and simplify
(4/7) x (7/8) = 28/56, or 1/2
1/2 is your answer
