Question

Convert the following 25 mm in to dm​

Answer 1

Answer: 0.25dm

Step-by-step explanation:

= 1 mm = 0.01 dm

= 25 mm = 25 x 0.01

= 0.25

Answer 2

Question:

Convert  25 mm in to dm.

Given:

The given Metric measure is 25mm

To Convert:

25mm to dm

Conversion Used :

$\textsf{1 mm }=10^{-2}dm$

$\textsf{1mm=10}^{-3}\\\\\\\textsf{1dm=10}^{-1}\\\\\\=10^{-3}\:mm={10}^{-1}dm\\\\\\=1dm={10}^{-3}\div10^{-1}mm\\\\\\=1dm={10}^{-3}\times10^{+1}\\\\\\\to a^m\times a^n=a^{m+n}\\\\\\=10^{-3+1}\\\\\\=10^{-2}$

Solution:

$\textsf{1 mm }=10^{-2}dm\\\\\\=\textsf{25mm}=10^{-2}\times 25\\\\\\\to a^{-n}=(\frac{1}{a})^n\\\\\\=(\frac{1}{10})^2\times25\\\\\\\to (\frac{a}{b})^m=\frac{a^m}{b^m}\\\\\\=\frac{1^2}{10^2}\times25\\\\\\=\frac{1}{100}\times25\\\\\\=\frac{25}{100}\\\\\\=0.25\: dm\\\\\\\boxed{=0.25\: dm}$

Answer:

25 mm = 0.25 dm
