A paper is 28cm long, how many meters is this?

1 m = 100 cm

28/100 = 0.28 m

Thank you, that's what my dad said but I didn't believe him :)

You're welcome.

Hehehe! Dads are always right, aren't they?

To convert centimeters to meters, you need to divide the number of centimeters by 100. In this case, the paper is 28 centimeters long. So, to calculate the length in meters, you would divide 28 by 100:

28 cm รท 100 = 0.28 meters

Therefore, the paper is 0.28 meters long.
