First, do multiplications and divisions in the order they appear from left to right.

$$-12 \times 1.6 \times 3 + 48 \div 3$$ $$= \color{red}{-12 \times 1.6} \times 3 + \color{red}{48 \div 3}$$ Start with the two operations in red. Copy everything else down tot eh next line.

Wait. I see the pic now.

5. mathstudent55

$$-12 \times \dfrac{1}{6} \times 3 + 48 \div 3$$ $$=\color{red}{-12 \times \dfrac{1}{6}} \times 3 + \color{red}{48 \div 3}$$ Do the two operations in red. Copy everything else as it is to the next line.

-12 * 1/6 = -2. Where did you get the 19.2 from?

11. pooja195

Have fun!

12. mathstudent55

$$=\color{red}{-12 \times \dfrac{1}{6}} \times 3 + \color{red}{48 \div 3}$$ Now you get this: $$=-2 \times 3 + 16$$ Now we do the multiplication: $$= - 6 + 16$$ Finally we add: $$= 10$$

14. mathstudent55

I had no idea this was a test. I don't see that stated anywhere.
