8 / 10 - 8
You asked:
Evaluate the expression: \(\frac{8}{10} - 8\)
MathBot Answer:
\[ \frac{8}{10} - 8 = - \frac{36}{5} = -7.2 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{8}{10}\) and \(\frac{-8}{1}\) is \(10\). \[ \begin{aligned} \frac{8}{10} - 8 &= \frac{8 \cdot 1}{10 \cdot 1} + \frac{-8 \cdot 10}{1 \cdot 10} \\ &= \frac{8 + -80}{10} \\ &= \frac{-72}{10} \\&= - \frac{36}{5} \end{aligned} \]
