Question

Find 21 ⅗% of 300 km

$21 \: 3 \div 5 \times 300$
​

Answer 1

Given: $21\ \frac{3}{5}\% \ of\ 300$

We have to solve the above equation.

• As we know that a percentage is a fraction of an amount is expressed as a particular number of hundredths of that amount.
• It is denoted by a symbol%.
• For example, $5$%means$\frac{5}{100}$.
• By using the unitary method we are calculating the percentage of numbers.
• As we know fractions can be converted into percentages and vice-versa.
• And percentages are reversible.  
• For example, $50 \% \ of\ 60$ is the same as$60 \% \ of\ 50$.

We are solving in the following way:

We have,

$21\ \frac{3}{5}\% \ of\ 300$

$=>\frac{105+3}{5} \%\ of\ 300\\\\=>\frac{108}{5} \%\ of\ 300\\\\=>\frac{108}{5}\times \frac{1}{100}\times 300\\\\=>\frac{27}{125} \times 300\\\\=>\frac{324}{5}$

Hence, $21\ \frac{3}{5}\% \ of\ 300$is$\frac{324}{5}$.
