Evaluate the expression: 0.2⋅3+0.086⋅5+0.8⋅0.914⋅−20.2 \cdot 3 + 0.086 \cdot 5 + 0.8 \cdot 0.914 \cdot -2

MathBot Answer:

0.2⋅3+0.086⋅5+0.8⋅0.914⋅−2=−10812500=−0.43240.2 \cdot 3 + 0.086 \cdot 5 + 0.8 \cdot 0.914 \cdot -2 = - \frac{1081}{2500} = -0.4324

0.2⋅3+0.086⋅5+0.8⋅0.914⋅−2=15⋅3+0.086⋅5+0.8⋅0.914⋅−2=35+0.086⋅5+0.8⋅0.914⋅−2=35+43500⋅5+0.8⋅0.914⋅−2=35+43100+0.8⋅0.914⋅−2=103100+0.8⋅0.914⋅−2=103100+45⋅0.914⋅−2=103100+45⋅457500⋅−2=103100+457625⋅−2=103100+−914625=−10812500\begin{aligned}0.2 \cdot 3 + 0.086 \cdot 5 + 0.8 \cdot 0.914 \cdot -2&=\frac{1}{5} \cdot 3 + 0.086 \cdot 5 + 0.8 \cdot 0.914 \cdot -2\\&=\frac{3}{5} + 0.086 \cdot 5 + 0.8 \cdot 0.914 \cdot -2\\&=\frac{3}{5} + \frac{43}{500} \cdot 5 + 0.8 \cdot 0.914 \cdot -2\\&=\frac{3}{5} + \frac{43}{100} + 0.8 \cdot 0.914 \cdot -2\\&=\frac{103}{100} + 0.8 \cdot 0.914 \cdot -2\\&=\frac{103}{100} + \frac{4}{5} \cdot 0.914 \cdot -2\\&=\frac{103}{100} + \frac{4}{5} \cdot \frac{457}{500} \cdot -2\\&=\frac{103}{100} + \frac{457}{625} \cdot -2\\&=\frac{103}{100} + \frac{-914}{625}\\&=\frac{-1081}{2500}\end{aligned}
