You asked:

Evaluate the expression: \(0.2 - 0.71\)

MathBot Answer:

\[ 0.2 - 0.71 = - \frac{51}{100} = -0.51 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{10}\) and \(\frac{-71}{100}\) is \(100\). \[ \begin{aligned} 0.2 - 0.71 &= \frac{2 \cdot 10}{10 \cdot 10} + \frac{-71 \cdot 1}{100 \cdot 1} \\ &= \frac{20 + -71}{100} \\ &= \frac{-51}{100} \end{aligned} \]
