$21.75 metres = 2175 centimetres$ $color(green)(21.75" metres "=2175" centimetres"$

Explanation:

It takes 100 cm to make 1 metre.

Using ratio:

$\frac{centimetres}{metres} \to \frac{100}{1} \equiv \frac{centimetres}{21.75}$ $("centimetres")/("metres") ->100/1 -=("centimetres")/21.75$

Write as:

$(\frac{100}{1} \times 1) \equiv \frac{centimetres}{21.75}$ $(100/1color(magenta)(xx1)) -=("centimetres")/21.75$

$(\frac{100}{1} \times \frac{21.75}{21.75}) \equiv \frac{centimetres}{21.75} = \frac{2175}{21.75}$ $(100/1color(magenta)(xx21.75/21.75)) -=("centimetres")/21.75 = 2175/21.75$

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So $21.75 metres = 2175 centimetres$ $21.75" metres"=2175" centimetres"$
