Problems from Fraction as a percentage

Calculate the following percentages:

  1. The $$30$$ per cent of $$50$$.
  2. The $$50$$ per cent of $$30$$.
  3. The $$20$$ per cent of $$32$$.
See development and solution

Development:

  1. We have to calculate the result of the operation $$50\cdot\dfrac{30}{100}$$, which is $$15$$.
  2. We have to c alculate the result of the operation $$30\cdot\dfrac{50}{100}$$, which is $$15$$.
  3. The result corresponds to calculate $$32\cdot\dfrac{20}{100}$$ which is equivalent to $$6,4$$.

Solution:

  1. $$15$$
  2. $$15$$
  3. $$6,4$$
