1 6/7

Step-by-step explanation:

2 3/5 ÷ 1 2/5

Change to improper fractions

2 3/5 = (5*2 +3)/5 = 13/5

1 2/5 = (5*1 +2)/5 = 7/5

13/5 ÷ 7/5

Copy dot flip

13/5 * 5/7

The 5's cancel

13/7

Change back to a mixed number

7/7 + 6/7

1 6/7

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
