To solve this question, you should know the rules of BEDMAS.
* Always work from left to right.
Using the rules of BEDMAS, I knew that I had to do the division part of the question first.
In order to do long division with decimals, you must change the decimals to whole numbers. The number of decimal places you move the decimal of the divisior, you must do the same to the dividend.
Now, you can use long division to figure out (-56) divided by 20. This game me an answer of 2.8.
The next step would be the multiplication.
Next, simply multiply the two decimals.
Please ignore the fact that I forgot the negative sign before 5.78.
Now that I have solved both the division and multiplication portions of the equation, I am left with:
To do the last step of this problem, what I did was use integer chips just to make it easier for myself. Then I subtracted 2.8 from 5.78. This gave me 2.98.
