The sum of the numerator and denominator of a fraction is greater by 1 than thrice the numerator. If the numerator is decreased by 1, then the fraction reduced to 1/3. find the fraction.​

3/7

Step-by-step explanation:

The numerator be 'x' and denominator be ' y'

then,

the sum of the numerator and denominator of a fraction is 3 less than the twice is x+y=2y-3 :- x-y+3=0 - equation 1

if the numerator and denominator is decreased by 1 then

x-1/y-1=1/2 :- 2(x-1) = 1(y-1) :- 2x-y-1=0 -equation 2

then equation 1 = equation 2

x-y+3=2x-y-1 :- x=4

from the equation 1

x-y+3=0 :- 4-y+3=0 :- y=7

there fore the fraction is 3/7

okay wait before i answer, is this for your points on a graph?
