1-0.20
You asked:
Evaluate the expression: \(1 - 0.20\)
MathBot Answer:
\[ 1 - 0.20 = \frac{4}{5} = 0.8 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{1}\) and \(\frac{-2}{10}\) is \(10\). \[ \begin{aligned} 1 - 0.20 &= \frac{1 \cdot 10}{1 \cdot 10} + \frac{-2 \cdot 1}{10 \cdot 1} \\ &= \frac{10 + -2}{10} \\ &= \frac{8}{10} \\&= \frac{4}{5} \end{aligned} \]
