Question

Convert $745$ cm into decimeters.

• A. $745dm$
• B. $0dm745cm$
• C. $7dm45cm$
• D. $74dm5cm$

Answer 1

The correct option is D $74dm5cm$

We know that, $1$ $decimeter=10$ $cm$, $1$ $cm=\frac{1}{10}$ $dm$

$745$ $cm=\frac{1}{10}\times 745$ $dm$

$=\frac{745}{10}$ $dm$

$=74.5$ $decimeter$ $=74$ $dm$ $5$ $cm$

So, Option $D$ is correct
