the denominator of a fraction is 8 greater than the numerator . if the numerator and the denominator are increased by 5 , the resulting fraction is equal to 6 â  „ 7 . what is the value of the original fraction ?
"let the numerator be x . then the denominator is x + 8 . x + 5 / x + 13 = 6 / 7 . 7 x + 35 = 6 x + 78 . x = 43 . the original fraction is 43 / 51 . the answer is d ."
divide(divide(subtract(multiply(6, add(5, 8)), 7), subtract(7, 6)), add(divide(subtract(multiply(6, add(5, 8)), 7), subtract(7, 6)), 8))
