You asked:

Evaluate the expression: \(1 - \frac{9}{20}\)

MathBot Answer:

\[ 1 - \frac{9}{20} = \frac{11}{20} = 0.55 \]


The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{1}{1}\) and \(\frac{-9}{20}\) is \(20\). \[ \begin{aligned} 1 - \frac{9}{20} &= \frac{1 \cdot 20}{1 \cdot 20} + \frac{-9 \cdot 1}{20 \cdot 1} \\ &= \frac{20 + -9}{20} \\ &= \frac{11}{20} \end{aligned} \]
