Answer:

[tex] \frac{15}{56} [/tex]

Step-by-step explanation:

We want to evaluate

[tex]xyz[/tex]

if

[tex]x = - \frac{4}{7} [/tex]

[tex]y = \frac{3}{4} [/tex]

[tex]z = - \frac{5}{8} [/tex]

We substitute these values to get:

[tex] - \frac{4}{7} \times \frac{3}{4} \times - \frac{5}{8} = \frac{15}{56} [/tex]

This is a proper fraction and

it is in the simplest form
