15 centimeters is equivalent to _________ millimeters.

Question

(Hint: 1 centimeter = 10 millimeters) PLZ!!! HELP ME!!!! THANK YOU!!! Also plz. explain it for me thank for the help!!!!

Answer 1

The hint is  1 cm = 10 mm

if you divide both sides by 1 cm or by 10mm

1 cm     10mm              1cm       10mm

-------  =  ---------  = 1 ..or -------  =  ---------  = 1

1 cm       1 cm              10mm     10mm

your equation is

15 cm = ? mm

You will be doing the following with the units:

cm * mm = mm

        -----

        cm

the cms will cancel leaving mm.

Basically, you are going to multiply 15 cm *1.

15 cm (10mm/1cm) = 150 mm

Answer 2

Well, if one centimeter is 10 millimeters, then you'd just multiply the number of centimeters by 10.  That will give you 150mm, which is the correct answer.  See if you can find the "metric conversion staircase" online somewhere...it helped me a lot when I was learning that stuff.  Actually, once you get used to it, metric is much easier to do conversions in than inches and feet are.  Good luck
