Question

How do you convert 90.8dm to mm?

Answer 1

Hint: In this problem, we have to convert the given decimetre value into its millimetre. Here dm is decimetre and mm is millimetre. We should know some unit conversions to solve these types of problems. Here we need unit conversion based on decimetre and millimetre. We know that one decimetre is equal to hundred millimetres, i.e.1dm=100mm. We can multiply the given decimetre value to hundred to convert it to its millimetre. . We should also remember that we have to write the correct unit after writing the final answer.

Complete step-by-step answer:
We know that we have to convert 90.8dm to mm.
Here we need unit conversion based on decimetre and millimetre.
We know that one decimetre is equal to hundred millimetres, i.e.1dm=100mm.
We can now multiply 100 to the given decimetre to convert into millimetre.
\[\begin{align}
  & \Rightarrow 1dm=100mm \\
 & \Rightarrow 90.8dm=90.8\times 100mm \\
\end{align}\]
We can now multiply the above step by moving the decimal points, we get
\[\Rightarrow 90.8\times 100=9080.0mm\]
Therefore, the answer is \[9080mm\].

Note: Students should remember some unit conversions to convert and find the answers for these types of problems. We should remember that one decimetre is equal to hundred millimetres, i.e.1dm=100mm, which is used in this problem. We should also remember some conversions like this to solve these types of problems. We should also remember that we have to write the correct unit after writing the final answer.
