So to simplify fractions, you have to divide the numerator and denominator by their common GCF, or Greatest Common Factor. You would keep going until the numerator and denominator don't have a GCF greater than 1.

The simplified fraction is 3/11.
Answer:
a. Alternate exterior angles.
b. <A and <B are congruent. This diagram involves a line intersecting two parallel lines, forming the congruent angles <A and <B on opposite sides of the transversal.
c. They are alternate exterior angles like <A and <B, but because it is not guaranteed that the transversal is intersecting parallel lines in this case, we cannot prove that <C and <D are congruent alternate exterior angles.
1/4 =2/8+3/8 =5/8
1-5/8=3/8
