You asked:

Evaluate the expression: \(\frac{18.10 - 17.87}{20}\)

MathBot Answer:

\[\frac{18.10 - 17.87}{20} = \frac{23}{2000} = 0.0115\]

\[\begin{aligned}\frac{18.10 - 17.87}{20}& = \left(18 + \frac{1}{10} - \left(17 + \frac{87}{100}\right)\right) \cdot \frac{1}{20}\\& = \left(18 + \frac{1}{10} - \frac{1787}{100}\right) \cdot \frac{1}{20}\\& = \left(\frac{181}{10} - \frac{1787}{100}\right) \cdot \frac{1}{20}\\& = \frac{23}{100} \cdot \frac{1}{20}\\& = \frac{23}{2000}\end{aligned}\]
