Problem

Simplify. \[ \frac{1+\frac{x}{x+1}}{1+\frac{x-1}{x+2}} \]

Solution

Step 1 :\[\frac{1+\frac{x}{x+1}}{1+\frac{x-1}{x+2}} = \frac{(x+1)+x}{(x+1)(x+2)} \div \frac{(x+2)+(x-1)}{(x+1)(x+2)}\]

Step 2 :\[= \frac{2x+1}{(x+1)(x+2)} \div \frac{2x+1}{(x+1)(x+2)}\]

Step 3 :\[= \frac{2x+1}{(x+1)(x+2)} \times \frac{(x+1)(x+2)}{2x+1}\]

Step 4 :\[= \frac{1}{1} = 1\]

Step 5 :\[\boxed{1}\]
