20 mm = 2 cm

Hence 220 cm - 2 cm = 18 cm

Remember the table in the Metric system

10 mm = 1cm

100 cm = 1 m

1000 m = 1 km

Each stage goes up in multiples of 10.

I think this is the right answer.

Lvl 2

20cm=200mm, 200-20=180

It is 180mm but we can simplify to 18cm

Lvl 4

Remember, 10mm= 1cm. So, just do 20-2= 18 cm

Because 2cm= 20mm
