5/10

3/12

6/9

4/11

2/13

Answer 2

< Answer >

Let the fraction be x/y

It is given that the denominator is 3 more than twice the numerator.

So, y=2x+3

And x+y=15

Substituting the value of y in the above equation,

x + 2x+3 = 15

So, 3x=15–3

So x=4

So, y = 2(4) + 3

So, y= 11

So, x/y = 4/11

Therefore, the fraction is 4/11.
