If 100 cm id 1 m than how many cm are there are 13m

The question requires you skills in doing multiplication or division. Ratio and proportion would also do here.
The topic here is about conversion.
You are given that 100 cm = 1m
Then how about 13 m?

100 cm : 1 m =  X : 13m
100 cm * 13m = 1m * x
1300 = 1m * X
X = 1300 cm

So 13m is equal to 1,300 cm
