You asked:

Evaluate the expression: \(1.75 - 2.1\)

MathBot Answer:

\[1.75 - 2.1 = - \frac{7}{20} = -0.35\]

\[\begin{aligned}1.75 - 2.1& = 1 + \frac{75}{100} - \left(2 + \frac{1}{10}\right)\\& = 1 + \frac{3}{4} - \left(2 + \frac{1}{10}\right)\\& = 1 + \frac{3}{4} - \frac{21}{10}\\& = \frac{7}{4} - \frac{21}{10}\\& = - \frac{7}{20}\end{aligned}\]
