50 cm is the same length as 500 mm

Explanation:

The same as Jim but using a ratio format in that of a fraction

Known: 1 cm = 10 mm

So instead of writing this like 1cm:10mm I write #(10mm)/(1cm)#

If we change the 1 cm into 50cm and maintain the ratio we have our answer.

Multiply by 1 and you do not change the value. However, 1 comes in many forms.

#color(green)((mm)/(cm) ->[10/1 color(magenta)(xx1)]" " -=" "[10/1color(magenta)(xx50/50)]#

The #-=# means equivalent to

So we now have #(mm)/(cm) -> 500/50#

So 50 cm is the same as 500 mm
