Question

b/a - c/b Given that a = 3, b = -5 and c = 6 evaluate each of the following expression.​

Answer 1

Answer:

$\frac{ - 7}{15}$

Step-by-step explanation:

Taking ${a=3,b=(-5) \:and\:c=6}$ and solving the above variables.

$\frac{b}{a} - \frac{c}{b} \\ \\ = \frac{ - 5}{3} - ( \frac{6}{ - 5} ) \\ \\ = \frac{ -5 }{3} + \frac{6}{5} \\ \\ lcm = 15 \\ \\ = \frac{ - 25 + 18}{15} \\ \\ = \frac{ - 7}{15}$
