Question

Express $54m$ as a percentage of $1km 80m$.

Answer 1

Hint: Use Conversion of units and express in terms of percentage. We know that in$1km$ there are $1000m$

Complete step-by-step answer:

First, we will convert both in $m$ first
we know that in $1km$ there are $1000m$

So, $1km80m = 1000 + 80 = 1080m$
Now we have to express in terms of percentage

Let the percentage be $x$
Therefore, $x\% $ of $1080$ is 54

In equation form we can write it as:
$
  \dfrac{{54}}{{1080}} \times 100 = x \\
  x = 5\% \\
$

Therefore, $54m$ is $5\% $ of $1080$.

Note: Whenever this type of question appears first do conversion of units as in this question first, we did conversion of units into $m$ after that we assumed $x$ as the required percentage and finally found its mathematical value after forming the equation.
