3m
Step-by-step explanation:
1 meter equals 100 cmWe know that
![1meter=100centimeters](/tpl/images/0920/7479/aab32.png)
Now how many (100 cm)'s are in (300 cm)'s? There are 3 right?So if every 100 cm is also a meter and there are 3 of these (100cm)s then they are just the same as 3 meters
![100cm=1m\\300cm=(x)m](/tpl/images/0920/7479/619cd.png)
cross multiply
![100cm(x)m=300cm1m](/tpl/images/0920/7479/5f8c8.png)
divide both sides by 100cm
