9 1/5-12/10
You asked:
Evaluate the expression: \(9\frac{1}{5} - \frac{12}{10}\)
MathBot Answer:
\[ 9\frac{1}{5} - \frac{12}{10} = 8 \]
The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{9}{1}\), \(\frac{1}{5}\), and \(\frac{-12}{10}\) is \(10\). \[ \begin{aligned} 9\frac{1}{5} - \frac{12}{10} &= \frac{9 \cdot 10}{1 \cdot 10} + \frac{1 \cdot 2}{5 \cdot 2} + \frac{-12 \cdot 1}{10 \cdot 1} \\ &= \frac{90 + 2 + -12}{10} \\ &= \frac{80}{10} \\&= 8 \end{aligned} \]
