You asked:

Evaluate the expression: \(0.09 \cdot 0 - 4.22\)

MathBot Answer:

\[0.09 \cdot 0 - 4.22 = - \frac{211}{50} = -4.22\]

\[\begin{aligned}0.09 \cdot 0 - 4.22& = \frac{9}{100} \cdot 0 - \left(4 + \frac{22}{100}\right)\\& = 0 - \left(4 + \frac{22}{100}\right)\\& = 0 - \left(4 + \frac{11}{50}\right)\\& = 0 - \frac{211}{50}\\& = - \frac{211}{50}\end{aligned}\]
