1.

the sum of the numerator and denominator of a fraction is 12 if 2 is added to both numerator and denominator the fraction becomes 1 by 4 find the fraction​

Answer»

Answer:

LET the NUMERATOR of the fraction be x and let the DENOMINATOR be y.

according to the question-

x+y=12(eq 1)

x+2/y+2=1/4

or

4x-y=-6 (eq2)

from eq 1 and 2 we get

x+y=12

4x-y=-6

5x=6

x=6/5

x=1.2

putting x value in eq 1 we get

1.2+y=12

y=12-1.8

y=10.2

the fraction is x/y= 1.2/10.8
