1/2 *1.2*0.8
You asked:
Evaluate the expression: \(\frac{1}{2} \cdot 1.2 \cdot 0.8\)
MathBot Answer:
\[\frac{1}{2} \cdot 1.2 \cdot 0.8 = \frac{12}{25} = 0.48\]
\[\begin{aligned}\frac{1}{2} \cdot 1.2 \cdot 0.8& = \frac{1}{2} \cdot \left(1 + \frac{2}{10}\right) \cdot \frac{8}{10}\\& = \frac{1}{2} \cdot \left(1 + \frac{1}{5}\right) \cdot \frac{8}{10}\\& = \frac{1}{2} \cdot \frac{6}{5} \cdot \frac{8}{10}\\& = \frac{3}{5} \cdot \frac{8}{10}\\& = \frac{24}{5} \cdot \frac{1}{10}\\& = \frac{12}{25}\end{aligned}\]
