Use digits to write seventeen billion and twenty-three ten thousadnths. Where is the zero in the hundredth's place?
And last one: 1/4 in. = 100 mi
1 1/4in = ? mi
+2446 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!
