[tex]1 \frac{1}{4} \div 0.6 = \frac{5}{4} \times \frac{10}{6} = \frac{50}{24} = 2 \frac{2}{24} = 2 \frac{1}{12} [/tex]
[tex] \frac{1}{5} \times 0.4 = 0.2 \times 0.4 = 0.08[/tex]
[tex] \frac{1}{4} + 0.3 = 0.25 + 0.3 = 0.55[/tex]
[tex]1 \frac{2}{3} \times 1.2 = \frac{5}{3} \times \frac{6}{5} = \frac{30}{15} = 2[/tex]
[tex] \frac{3}{8} - 0.15 = 0.375 - 0.15 = 0.225[/tex]
