Question

The length of a young gram plant is 65 mm. Express its length in cm

Answer 1

Hint: We have asked to convert 65 mm into centimetres . To convert millimetres to centimetre we need to divide it by 10.

Complete step-by-step answer:
The length of the plant is given in millimetres
We need to convert millimetres into centimetres
We know that 10 millimetres = 1 centimetre
So in order to convert millimetres into centimetre we need to divide it by 10
$ \Rightarrow \dfrac{{65}}{{10}} = 6.5cm$
Therefore 60 mm can be written as 6.5 cm
Hence the length of the young gram plant is 6.5 cm.

Note: To convert centimetre to millimetre we need to multiply it by 10
To convert centimetre to metre we need to divide by 100
To convert metre to centimetre we need to multiply by 100
To convert metres to kilometres we need to divide by 1000
To convert kilometres to metres we need to multiply by 1000
