How do we solve complex fractions?

When you see a complex fraction , it usual consists of another fraction for example;
1/1/3
The first step its rewrite it as 1 divided by 1/3

Then you do the reciprocal to the "1/3" so you can turn the divisor bar into multiplication so it become 3/1 or 3
Then it becomes1*3 and the end result is 3

Try with another example :
1/1/x+1
so first write it as 1 divided by 1/x+1
then do the reciprocal to change the sign so it becomes multiplication ; 1* x+1
now multiply and your result becomes x+1
