Step-by-step explanation:

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:-  $20 \mathrm{~kg}\ x\ \%\ of }\ 80 \mathrm{~kg}.$

             To find:-Value of given expression=?

             Solution:-

• A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.

• It is denoted by %.

• We are using the unitary method to calculate the percentage of numbers.

• Fractions can be converted into percentages and vice-versa.

        Therefore,

        $20 \mathrm{~kg}\ x\ \%\ of }\ 80 \mathrm{~kg}\\=>\frac{x}{100} \times80\ kg=20\ kg\\=>\frac{80x}{100} =20\\=>80x=20\times100\\=>80x=2000\\=>x=\frac{2000}{80}\\=>x=25\%$

     Hence we will get the $20 \mathrm{~kg}\ 25\ \%\ of }\ 80 \mathrm{~kg}.$
