# How to convert USD (United States Dollars) to Euro Currency?

#### Explanation:

From the net 9-3-2018

Using the above values we have:

$\textcolor{b l u e}{\text{Ratio in horizontal format of ratio:}}$

$: € =$1color(white)("."):color(white)(".")0.812652 €

We need $12.87 so multiply both parts by that amount $1xx12.87color(white)(".") :color(white)(".") 0.812652€xx12.87
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$\textcolor{b l u e}{\text{Ratio in fraction format ( I much prefer this approach )}}$

$/€ ->($1)/(€0.812652)

For multiply or divide what you do to the top you also do to the bottom

$/€ ->($1)/(€0.812652)-=($1xx12.87)/(€0.812652xx12.87 ($12.87)/(€10.45883125)

Rounding to 2 decimal places we have:

\$12.87 =€10.46 to 2 decimal places
