17000000000.0023 is 17 billion and twenty-three ten thousandths written out.

 

\(1\frac{1}{4}in=500mi\)

 

Let's set up a proportion to solve:

 

\(\frac{\frac{1}{4}}{100}=\frac{1\frac{1}{4}}{x}\)  Cross multiply and solve

\(\frac{1}{4}x=100*1\frac{1}{4}\)  Convert mixed fraction to an improper one

\(\frac{1}{4}x=\frac{100}{1}*\frac{5}{4}\)  Simplify the right side of the equation

\(\frac{1}{4}x=\frac{500}{4}\)  Multiply both sides by 4 to get rid of the pesky fractions

\(x=500\)

 

Therefore, if 1/4in=100mi, then 1 1/4in=500mi!
