Question

1. \\(\frac{b - 5}{4b - 20}\\)

Explanation:

Step1: Factor the denominator

Factor out 4 from \(4b - 20\), we get \(4(b - 5)\). So the fraction becomes \(\frac{b - 5}{4(b - 5)}\).

Step2: Cancel common factors

Assuming \(b
eq5\) (to avoid division by zero), we can cancel the common factor \((b - 5)\) from the numerator and the denominator.

Answer:

\(\frac{1}{4}\) (for \(b
eq5\))
