Question

A fraction becomes 1/3 when 1 is subtracted from the numerator and it becomes 1/4 when 8 is added to its denominater Find the fraction​

Answer 1

Answer:

Fraction= 5/12

Explanation:

let the numerator be x

denominator be y

acc to given condition

x - 1 /y = 1/3 ......eq.(1)

x/ y+8 = 1/4 .....eq (2)

from eq 1 and 2 we get

3x-y =3 ....(4)

4x-y = 8 .....(5)

(-) (+) (-) like this

nothing u have to do just change the sign ok!!

from eq 4 and 5 we get

-x = -5

x = 5 ok.

putting x value in eq 4 either u can put on 5 also

but in any of one eq u have to put ..

sooo,

3(5) - y = 3

15 -y = 3

-y = 3-15

-y= -12

y = 12 ok...

so as we know

Fraction= x/y = 5 /12 is the answer dear
