Question

1. The denominator of a rational number is 2 less than twice the numerator. If numerator and
denominator are increased by 1 each the rational number becomes
4/5
Find the number.
​

Answer 1

Answer:

Let the numerator be x

ATP:-

=x/2x-2

=x+1/2x-2+1= 4/5

= 5(x+1)=4(2x-2+1) (Cross multiplication)

=5x+5= 8x-4

= 5x-8x= -4-5

= -3x= -9

= x= -9/-3

=x= 3

Hope it is right...
