9-.7
You asked:
Evaluate the expression: \(9 - .7\)
MathBot Answer:
\[ 9 - .7 = \frac{83}{10} = 8.3 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{9}{1}\) and \(\frac{-7}{10}\) is \(10\). \[ \begin{aligned} 9 - .7 &= \frac{9 \cdot 10}{1 \cdot 10} + \frac{-7 \cdot 1}{10 \cdot 1} \\ &= \frac{90 + -7}{10} \\ &= \frac{83}{10} \end{aligned} \]
