1)

[tex]a = - 2.4 \\ b = 3.7 \\ |a| + |b| = | - 2.4| + |3.7| = 2.4 + 3.7 = 6.1[/tex]

2)

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

3)

[tex]a = \frac{1}{2} \\ b = - \frac{1}{6} \\ |a| - |b| = | \frac{1}{2} | - | - \frac{1}{6} | = \frac{1}{2} - \frac{1}{6} = \frac{3}{6} - \frac{1}{6} = \frac{2}{6} = \frac{1}{3} [/tex]
