The sum of the numerator and the denominator of the certain fraction is equal to 4,140. When the fraction was reduced, the result was 7/13 . What was the original fraction?

numerator = 1449 denominator = 2691

Step-by-step explanation:

let numerator = n, denominator = d

n/d = 7/13

or n = 7d/13 (i)

again, n+d = 4140

or 7d/13 +d = 4140 [substituting the value in (i)]

or 20d/13 = 4140

or d = 2691

n = 4140 - 2691 = 1449

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

answer

false
