Question

if numerator of a fraction is increased by 10% and denominator is decreased by 12% then the outcome is 15/64. Find the fraction?​

Answer 1

Answer:

Step-by-step explanation:

Let the numerator be x and the denominator be y

__x_+_10%x__ = _15_

y + 12%y 64

x + 10x/100 = 15

(100x +10x)/100 = 15

110x = 15 × 100

110x = 1500

x = 1500/ 110

x = 13.64

y - 12y/100 = 64

(100y - 12y)/100 = 64

88y/100 = 64

88y = 64 × 100

88y = 6400

y = 6400/88

y = 72.73

Fraction = 13.64/72.73
