Question

Evaluate $ 10\% $ of $ 5 $ litres.

Answer 1

Hint: As we know that a percentage is a number or ratio expressed as a fraction of $ 100 $ or as a ratio of any value to the whole value multiplied by $ 100 $ . It is denoted by using the percent sign, $ \% $ . The abbreviations used to represent the percentage id “pct” or “pc”. A percentage is a dimensionless number means it has no unit of measurement. Here we have to find the value of the expression which includes multiplication.

Complete step-by-step answer:
Here we have to find the value of $ 10\% $ of $ 5 $ litres.
The first part is $ 10\% $ . It can be written as $ \dfrac{{10}}{{100}} $ .
In between we have “of” it means to multiply.
Now we can put the expressions together and we have
 $ \dfrac{{10}}{{100}} \times 5 = 0.5L $ .
Hence the required answer is $ 0.5\;L $ .
So, the correct answer is “ $ 0.5\;L $ ”.

Note: If the number is given in fraction then either we assume a percentage number or by conversing the fraction into decimal form then multiplying by $ 100 $ . We can also write the above answer in millilitres. We know that $ 1L = 1,000ml $ , so by applying this we can write $ 0.5L $ into millilitres as $ \dfrac{{0.5}}{{1000}} = 500ml $ .
