The numerator of a fraction is 1 more than twice its denominator. if 4 is added to both the numerator and the denominator, the fraction reduces to 5/3. find the denominator

(2d + 1) / d

(2d + 1 + 4) / (d + 4) = 5/3
(2d + 5) / (d + 4) = 5/3
3(2d + 5) = 5(d + 4)
6d + 15 = 5d + 20
6d - 5d = 20 - 15
d = 5

(11 + 4) / (5 + 4) = 5/3
15/9 = 5/3
5/3 = 5/3 (correct)

ur numerator is 11, ur denominator is 5adding 4 to each gives u 15/9, which reduces to 5/3

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees
