Question
The numerator of a fraction is 9 less than its
denominator. If the numerator is decreased by 4 and the denominator is increased by 2, then the denominator is 16 times the numerator. Find the fraction?Solution
Let denominator be x and then numerator be x – 9 ∴16(x – 9 – 4) = x + 2 16(x – 13 ) = x + 2 16x – 208 = x + 2 x = 210 /15 = 14 Fraction = 5 /14
