Answer 2

to do this, you notice you have
52 in

if you multiply by a number that has units cm/in
the "in" cancel

start with
1 in = 2.54 cm
you want a ratio that has cm on top, so write the ratio
\[ \frac{2.54 \ cm}{1 \ in} \]
next multiply
\[ 52 \ \cancel{in} \cdot \frac{2.54 \ cm}{1 \ \cancel{in}} \]
