Respuesta :

1+ 1/y÷1-1/y = y+1 /y÷y-1/y  =  y+1/ y-1

Answer:

[tex]\frac{y+1}{y-1}[/tex]

Step-by-step explanation:

[tex]\frac{1+\frac{1}{y}}{1-\frac{1}{y}}[/tex]

First we simplify the numerator

[tex]1+\frac{1}{y}[/tex], make the denominators same

[tex]\frac{1*y}{1*y}+\frac{1}{y}[/tex]

[tex]\frac{y+1}{y}[/tex]

now we simplify the denominator

[tex]1-\frac{1}{y}[/tex], make the denominators same

[tex]\frac{1*y}{1*y}-\frac{1}{y}[/tex]

[tex]\frac{y-1}{y}[/tex]

[tex]\frac{\frac{y+1}{y}}{\frac{y-1}{y}}[/tex]

both top and bottom have same denominator y so we cancel it out

[tex]\frac{y+1}{y-1}[/tex]
