A large spool holds 78.5 meters of steel cable. How many centimeters of cable does the spool hold?

OpenStudy (caominhim):

there are 100 centimeters per meter, we know that because centi is 1/100th

OpenStudy (caominhim):

if you have 78.5 meters and there are 100 centimeters per meter, multiply your meters by 100 centimeters because 1 meter = 100 centimeters

OpenStudy (ops2242005):

so the answer is 7850

OpenStudy (caominhim):

yes
