D. fill 3/10 for r so
[tex] - 4 \frac{4}{9} ( \frac{3}{10} )[/tex]
[tex] - \frac{36 + 4}{9} \times \frac{3}{10} [/tex]
[tex] - \frac{40}{9} \times \frac{3}{10} [/tex]
[tex] - \frac{120}{90} [/tex]
[tex] - \frac{4}{3} \: or \: - 1 \frac{1}{3} [/tex]

E. fill -2(2/3) for W
[tex] - 3 \frac{1}{8} ( - 2 \frac{2}{3} )[/tex]
[tex] \frac{ - 24 + 1}{8} \times \frac{ - (6 + 2)}{3} [/tex]
[tex] - \frac{25}{8} \times \frac{ - 8}{3} [/tex]
[tex] - \frac{ - 200}{24} [/tex]
[tex] \frac{25}{3} \: or \: 8 \frac{1}{3} [/tex]
F. fill (-3/4)
[tex] ((\frac{3}{8} )( \frac{ - 3}{4} )) + (( \frac{1}{8} )( \frac{ - 3}{4} ))
[/tex]
[tex] \frac{3 \times - 3}{8 \times 4} + \frac{1 \times - 3}{8 \times 4} [/tex]
[tex]- \frac{9}{32} - \frac{3}{32}[/tex]
[tex] - \frac{12}{32} = - \frac{3}{8} [/tex]
