Answer:
[tex]A. \frac{5280*12}{0.394}cm[/tex]
Explanation:
1. Take the quantity you want to convert:
[tex]1mile[/tex]
2. Multiply by the first conversion factor:
[tex]1mile*\frac{5280feet}{1mile}[/tex]
3. Apply the second conversion factor:
[tex]1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}[/tex]
4. Multiply by the third conversion factor:
[tex]1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}*\frac{1centimeter}{0.394inches}[/tex]
5. Multiply all the numerators and divide by denominators:
[tex]1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}*\frac{1centimeter}{0.394inches}=\frac{5280*12}{0.394}cm[/tex]
