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

It takes 100 cm to make 1 metre.

Using ratio:

#("centimetres")/("metres") ->100/1 -=("centimetres")/21.75#

Write as:

#(100/1color(magenta)(xx1)) -=("centimetres")/21.75#

#(100/1color(magenta)(xx21.75/21.75)) -=("centimetres")/21.75 = 2175/21.75#

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

So #21.75" metres"=2175" centimetres"#
