1)

[tex] | - 2.4| + |3.7| = 2.4 + 3.7 = 6.1[/tex]

2)

[tex] | - 1 \frac{1}{3} | \times | - \frac{4}{3} | = 1 \frac{1}{3} \times \frac{4}{3} = \frac{4}{3} \times \frac{4}{3} = \frac{16}{9} = 1 \frac{7}{9} [/tex]

3)

[tex] | \frac{1}{2} | - | - \frac{1}{6} | = \frac{1}{2} - \frac{1}{6 } = \frac{6}{12} - \frac{2}{12 } = \frac{4}{12 } = \frac{1}{3} [/tex]
