7. The denominator of a fraction is 1 more than twice its numerator. If the numerator and denominator are both increase by 5 it becomes 3/5 find the original friction
​

Answer 1

Answer:

friction 2 is answer rhanks

Answer 2

Let the numerator be x. Then it's denominator is 2x-1

If the numerator and the denominator both increased by 1 the fraction becomes 3/5.

So (x+1)/(2x-1+1) = 3/5

ie (x+1)/2x = 3/5 => 6x = 5x + 5 => x = 5

So the numerator is 5 and hence the denominator is 2×5 - 1= 9

So the fraction is 5/9
