Question

Express

$80$ cm as a percentage of $4$m

Answer 1

Here we have to find the percentage of $80$ cm out of $4$m

So first, you have to convert $4$m into cm

i.e- $4m=4\times 100cm=400cm$ [ $1m=100cm$]

To convert the following into a percentage, we have to multiply it by $100$

i.e- $\frac{80}{400}\times 100\%=\frac{80}{4}\%=20\%$

Hence On Expressing $80$ cm as a percentage of $4$m is $20\%$
