Answer 2

Question :

How many centimetres makes up $\sf 4 \dfrac{1}{2} \: metres?$

⠀⠀ ⠀

Understanding Question :

In the given question, we have to find that how many centimetres are in $\sf 4 \dfrac{1}{2} \: metres?$

First of all, we have to covert given mixed fraction into simple fractional form and then convert it into centimetres by multiplying 100 centimetres in the resulting number.

⠀⠀ ⠀

Answer :

First of all, we know that :

1 metre = 100 centimetres

⠀⠀ ⠀

Now, we have to find :

• $\sf 4 \dfrac{1}{2} \: metres = ? \: centimetres$

⠀⠀ ⠀

$\sf As, \: 4 \dfrac{1}{2} \: metres = \dfrac{9}{2} \: metres$

⠀ ⠀⠀ ⠀

$\sf : \implies 4 \dfrac{1}{2} \: metres = \dfrac{9}{2} \times 100 \: centimetres$

$\sf : \implies 4 \dfrac{1}{2} \: metres = \dfrac{9}{\cancel{2}} \times \cancel{100} \: centimetres$

$\sf : \implies 4 \dfrac{1}{2} \: metres = \dfrac{9}{1} \times 50 \: centimetres$

$\sf : \implies 4 \dfrac{1}{2} \: metres = 9 \times 50 \: centimetres$

$\sf : \implies 4 \dfrac{1}{2} \: metres = 450 \: centimetres$

$\large \underline{\boxed{\bf{4 \dfrac{1}{2} \: metres = 450 \: centimetres}}}$

⠀⠀ ⠀

Hence, 450 centimetres makes up $\bf 4 \dfrac{1}{2} \: metres.$
