they wanted me to choose an equivalent measure for 150 centimeters and they got 1500mm. How did they arrive at the answer??

There are 10 milimeters (mm) in each centimeter (cm). By multiplying 10 times 150, we get the number of mm in 150 cm -- 1500 mm.

I don't really understand what you mean by what you say when you say there are 10 milimeters(mm) in each centimeter(cm). But I do understand when you say 150*10=1500mm. I don't know or understand my measures and i don't even know what mm and cm measures up to. Are cm and mm big or small measures??

If you look at a ruler with centimeters and milimeters, you'll see ten little marks in each centimeter. Check this site for a picture.

My fingernail is about 1 centimeter (cm) wide. Lead in an automatic pencil is less than a milimeter (mm) wide.

how many centimeters is in a meter

100 centimeters

Centimeters (cm) and millimeters (mm) are units of measurement used to describe length or distance. They are both smaller units of measurement, with millimeters being smaller than centimeters.

To understand how many millimeters are in a centimeter, you can visualize a ruler. On a ruler, there are 10 equally spaced marks between each centimeter. These marks represent millimeters. So, for every centimeter, there are 10 millimeters.

In the case of converting 150 centimeters to millimeters, you can multiply the number of centimeters (150) by the conversion factor of 10 (the number of millimeters in a centimeter).

150 centimeters x 10 millimeters/centimeter = 1500 millimeters

Therefore, 150 centimeters is equivalent to 1500 millimeters.
