Question from gayle, a parent:

150 decimeters is how many centimeters

Hi Gayle,

Look at Steve's list of metric prefixes. It gives

deci- (d-) 10-1 tenth
centi- (c-) 10-2 hundredth

Thus a decimeter is one tenth of a meter and a centimeter is one one-hundredth of a meter. Thus it takes 10 centimeters to make a decimeter and thus 1500 centimeters to make 150 decimeters.
