Answer 2

Given,

Length of a pencil = 15 cm

To find,

The length of the given pencil into 'metre' unit.

Solution,

We can simply solve this numerical problem by using the following process.

Here, we will need the mathematical relationship between the centimetre and metre. Which is -

100 centimetres = 1 metre

The rest of the calculations will be in normal arithmetic method.

So,

1 centimetre = (1/100) metre

15 centimetres = (15/100) metre = 0.15 metre

[This will the required value of the length of the pencil in metre unit.]

Hence, the length of the pencil is 0.15 metre
