What is the value of the underlined digit 0.812 as a fraction

I unsure about which digit is underlined but suppose it is all three 812. Then the correct representation as a fraction is 812/1000. If the undwrlined digit was just the 8 it would be 8/10. 1 would be 1/100, and 2 would be 2/1000.

i dont know

step-by-step explanation:

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
