Question

Convert $105$ mm into hectometre.

Answer 1

We know that ,

$1$ hectometre = $100000$ mm

$\Rightarrow$ $1$ mm =$\frac{1}{100000}$ hectometre

$\Rightarrow$ $105$ mm = $\frac{105}{100000}$hectometre

$\Rightarrow$ $105$ mm = $0.00105$hectometre ( since ,when number gets divided by 100000 , then decimal point shifts five places to the left )

Thus , conversion is $0.00105$ hectometre .
