Required:
Solve
Solution:
[tex] \frac{-1}{5} * (\frac{3}{4} + \frac{1}{7}) [/tex]
Apply distributive property by multiplying each reaction in the box by -⅕
[tex] (\frac{-1}{5} * \frac{3}{4}) + (\frac{-1}{5} * \frac{1}{7}) [/tex]
[tex] \frac{-3}{20} + \frac{-1}{35} [/tex]
Add together. Common denominator is 140. Therefore:
[tex] \frac{-21 + (-4)}{140} [/tex]
[tex] \frac{-25}{140} [/tex]
Simplify further
[tex] \frac{-5}{28} [/tex]
