Question

How do you change $75$ millimeters to decimeters?

Answer 1

Hint: In order to change $75$ millimeters to decimeters, we know that one decimeter is equal to $100$ millimeter, so to convert millimeters to decimeters, we will divide the given value by $100$ . Thus, we will get the required value.

Complete step-by-step answer:
If we need to convert one millimeter to decimeter, then we need to multiply the value of the decimeter with $100$ i.e., $1dm=1mm\times 100$ .
The decimeter is a unit of length in the metric system, equal to one tenth of a meter. The common non-SI metric unit of volume, the liter, is defined as one cubic decimeter. A decimeter is not as widely used, but is not as widely used, but is an important unit. In real life, we rarely find measurements written in decimeters. Decimeter is a unit larger than millimeter and centimeter. In the increasing order of units, the decimeter is in the third position and further the units.
Now, we need to convert $75$ millimeters to decimeters.
Generally, we know that one decimeter is equal to $100$ millimeter, so to convert millimeters to decimeters, we have to divide the given value by $100$ .
Thus, we have,
 $75mm={\displaystyle \frac{75}{100}}dm$
 $75mm=0.75dm$
Hence, the value of $75$ millimeters is $0.75$ decimeter.
So, the correct answer is “ $0.75$ decimeter”.

Note: The millimeter is a unit of length in the metric system, equal to one thousand of a meter, which is the SI base unit of length. Therefore, there are one thousand millimeters in a meter. There are ten millimeters in a centimeter. Millimeters are used to measure very small but visible-scale distances and lengths. In terms of real-world comparisons, a millimeter is roughly the size of the wire used in a standard paper clip. It is used throughout the world in the sciences and is the standard of measurement for science engineering, technology and mathematics (STEM).
