I am writing a computer program for school, and although this sounds silly, I don’t know what the actual math process for money conversion is.
Example: 1 US Dollar = 9.5085 Mexican Pesos
What is the math process to get this? Is it division? If so, what is divided?
In general, you always have the right to multiply a quantity by one. It does not change the quantity, but it may change the way it looks. The issue is: how do you write 1?
One, can be written as 1, 1/1, 2/2, 3/3, etc. Something over itself is 1. Lets extend that. Something over its equivalent is 1.
Thus 1 USD/9.5065 MP is 1, and so is 9.5085 MP/1 USD. The 1 to use is the one that cancels units properly.
5USD x 9.5085 MP/1 USD = 47.5425 MP since the USD cancel
5MP x 1 USD/9.5085 MP = 0.5258…. USD ~ about 53 cents since the MPs cancel.
Let the units tell you which 1 to use.
Does this help?

you multiply or divide depending on which conversion and which figur eyou have…
so if you have $232, multiply 232*9.5085
if you have 6,032 peso, you divide 6032/9.5085
if you have a revires and only want to use multiplication that can be done too.
this is 4th grade math.
