The denominator of a fraction is 4 more than the numerator. If the denominator is increased by 1 and the numerator is decreased by 1, then the fraction becomes4/7. Find the fraction.
Answers
Answer:
Step-by-step explanation:
Let numerator be x and denominator Y
y= x+4 ------------1
given
(x-1)/(y+1) = 4/7
cross multiplying
7x-7 = 4y+4
7x-11=4y
Putting value of y from EQUATION 1
7x -11= 4x +16
3x = 27
x = 9
putting x value in equation 1
y = 9+4
y=13
therefore the fraction is 9/13
CHEERS, PLease do mark brainliest
the denominator is 4 more than numerator
denominator increased by 1 then a+1=d
numerator is decreased by 1 then x-1=n
fraction became 4/7
so the denominator
=a+1
=a-1 to find previous no we
=7-1 subtract
=6 is the denominator
numerator
=n-1
=n+1to find after no we add
=4+1
=5 is the numerator
then the fraction is 5/6
as 5-1=4
6+1=7
