[tex]3\frac{75}{100} \div \frac{125}{100} \times \frac{80}{100} \\ = \frac{375}{100} \times \frac{100}{125} \times \frac{80}{100} \\ = \frac{375 \times 80}{125 \times 100 } \\ = \frac{30.000}{12.500} \\ = 2,4[/tex]

[tex]3 \frac{3}{1} \div \frac{125}{100} \times \frac{4}{5} = 3 \frac{3}{1} \div \frac{100}{125} \times 4 = 27 \times \frac{20}{125} \times 4 = 27 \times \frac{4}{25} \times 4 = \frac{432}{25} = 17 \: 7per25= 17.28[/tex]
