Calculate the following percentages:
- The $$30$$ per cent of $$50$$.
- The $$50$$ per cent of $$30$$.
- The $$20$$ per cent of $$32$$.
See development and solution
Development:
- We have to calculate the result of the operation $$50\cdot\dfrac{30}{100}$$, which is $$15$$.
- We have to c alculate the result of the operation $$30\cdot\dfrac{50}{100}$$, which is $$15$$.
- The result corresponds to calculate $$32\cdot\dfrac{20}{100}$$ which is equivalent to $$6,4$$.
Solution:
- $$15$$
- $$15$$
- $$6,4$$
