The correct option is A Yes
We have to find the ratio of 200 cm and 1 m.
200cm and 1m have different units, let's convert them to same units in order to find the ratio.
We know,
1 m=100 cm
multiply both sides by 2
1 m×2=100 cm×2
2 m=200 cm
Now, the ratio of 200 cm and 1 m
⇒200cm1m=2m1m=2:1
Hence the given statement is true.
