You asked:

Evaluate the expression: \(3 - 0.7\)

MathBot Answer:

\[ 3 - 0.7 = \frac{23}{10} = 2.3 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{3}{1}\) and \(\frac{-7}{10}\) is \(10\). \[ \begin{aligned} 3 - 0.7 &= \frac{3 \cdot 10}{1 \cdot 10} + \frac{-7 \cdot 1}{10 \cdot 1} \\ &= \frac{30 + -7}{10} \\ &= \frac{23}{10} \end{aligned} \]
