Neither step above makes sense.
You seem to be saying that there are 11 pesos per dollar. (That is NOT
11%).
To convert $ to peso, multiply by 11. To convert from pesos to
dollars, divide by 11.
If you took any quantitative science in high school or college, you
should have learned a little tool called dimensional analysis (or
factor label, or such). This is a great place for it.
