Divide. Why? See below:

$2$ weeks$/$year$?$ Answer:

Weeks $*$ weeks$/$year $=$ weeks $\frac{2}{?}$ year

Weeks divided by weeks$/$year $=$ weeks$/($weeks$/$year$)=$ weeks $*$ year$/$weeks $=$ years

Here are some useful numbers for part $1$:

Days per year: $365$ Hours in one day

$24$ Days in one week: $7$

One meter: $3\mathrm{.}28$ feet

One mile: $5280$ feet

One mile: $1\mathrm{.}60934km$

Question $1$: Which is the correct mathematical operation needed to convert from miles to $km?$ Show your work using units as in the example above.
