Question

If a numerator of a fraction is incraesed by 1 its become 3/4 if the denominator is increased by 2 its value become 1/2 find the fraction.
plz solve it tomorrow is my prelims

Answer 1

let assume  X  is numerator

and let assume Y is denominator

and fraction will become like this numerator/denominator

fraction=a

a=X/Y

----------------------------------------------------------------------------------------------

Y+X=3/4

==>X+Y=3/4

4X+4Y=3 --->A)

----------------------------------------------------------------------------------------------

X+2Y=1/2

2X+4Y=1 -->B)

subtract equation A and equation B

we WILL GET

4X+4Y=3

2X+4 =1

2x =2

2x=2

x=2/2

x=1

put x=1 in eq A

we will  get

2*(1)+4Y=1

2+4Y=1

4Y=1-2

4Y=-1

Y=-1/2

fraction we know that x/y so that

1/-1/4

x//y=-4/1
