When you divide 287 by 68, when it is not rounded, you will get 4.22058823529... (repeated decimal), but when you round it, you can either get the following: 4.22, 4.2, or 4 (choose which ever you want to pick out of these rounded forms.)
Hope this helped!

Well depending on the equation you look at both sides and eliminate everything from both using addition, subtraction, multiplication, and division.
Ex:
3c-4=7 first add the 4 because you use the opposite type of operation so you add it to 7 which gives you:
3c=11 next you have to divide to get it alone
3c/3=11/3
which gives you
c= 3.66666666667
18- 4/9 = 17 9/9 - 4/9 = 17 5/9 litters
6 ibls = 96 ounces
so <span>6ibls divided by 10ounces =9.6 ibls</span>
X= (-40,0)
y= (0,15)
May God bless you and your family
