Answer 1

The answer is A which comes out to about 160812 cm

Answer 2

Answer:

$A. \frac{5280*12}{0.394}cm$

Explanation:

1. Take the quantity you want to convert:

$1mile$

2. Multiply by the first conversion factor:

$1mile*\frac{5280feet}{1mile}$

3. Apply the second conversion factor:

$1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}$

4. Multiply by the third conversion factor:

$1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}*\frac{1centimeter}{0.394inches}$

5. Multiply all the numerators and divide by denominators:

$1mile*\frac{5280feet}{1mile}*\frac{12inches}{1foot}*\frac{1centimeter}{0.394inches}=\frac{5280*12}{0.394}cm$
