Which is larger 1 meter or 105 centimeters?
amm1812
"centi" means "hundredth". Think "cent" as in "penny". There are 100 cents or 100 pennies in a dollar.

That helps me remember that 
1 meter = 100 centimeters

The original "1 meter or 105 centimeters" turns into "100 centimeters or 105 centimeters"

At this point, it is clear that 105 is larger than 100. So 105 cm is larger than 1 meter.
