[tex]a) \frac{25}{100} \times 100 = 25 [/tex]

[tex]b) \frac{30}{100} \times 12.05 = \frac{30}{100} \times \frac{1205}{100} [/tex]

[tex] = \frac{3}{20} \times \frac{241}{10} [/tex]

[tex] = \frac{723}{200} [/tex]

[tex]c) \frac{40}{100} \times 60 = 4 \times 6 = 24[/tex]

[tex]d) \frac{32}{100} \times 3 \frac{1}{3} = \frac{32}{100} \times \frac{10}{3} = \frac{320}{300} = \frac{16}{15} [/tex]

[tex]e) \frac{0.1}{100} \times 10 = \frac{1}{10} \times \frac{1}{100} \times 10 = \frac{1}{100} [/tex]
