sally's pencil is 15 hundredths of a meter long(0.15).Edward's pencil is 2 tenths a meter long(0.2).whose pencil is longer?

0.2 = 0.20 = twenty hundredths
Which is longer? 
but why is 2.0 bigger than 0.15?

Which is more?
15 cents (0.15) or 20 cents (0.20)? 
Edwards because 0.2= 0.20 or 0.200 or 0.2000. It equals the same thing no matter how many zeros there are.
