What is 4 6/8+11 1/3

6 0

So 4 6/8= (32/4)+6/8=38/8
11 1/3=(33/3)+1/3=34/3
so 38/8+(34/3)

to add you must get the bottom number equall so

114/24+272/24=386/24=16 1/12

Well, first of all you would need to find common denominators. Obviously 8 and 3 have a common denominator of 24, because 8 times 3 equals 24. Now, for the 4 6/8 the whole number (4) would stay the same, but the fraction would turn into 18/24 because you multiplied the denominator by three, and whatever you do to the bottom you must do to the top. For the 11 1/3 it would be 11 8/24 because the whole number (11 would stay the same while, again, you multiply both the top and bottom by 8. So, the problem would turn into 4 18/24 + 11 8/24, which equals 15 26/24. This would then simplify to 18 23/24.

Answer:

Step-by-step explanation:

I find it hard to believe that you were asked to find the solution to a cubic by any other method than graphing it, which I have given below. Not only that, the numbers are very awkward.

The best you could do I think is equate the two equations after you have looked at the graph.

The x value must satisfy

0.5(x - 4) = 2x^3 - 2x - 3

0.5x - 2 = 2x^3 - 2x - 3

2x^3 + 0.5x - 2x - 3 +2 = 0

3x^3 - 1.5x - 1 = 0

from which you can get y

My calculator gives the solution as

x = 0.5

y = - 1.75

I have corrected the mistake I made doing this. The answer is now correct. The graph shows the original two equations which agrees with the combined equation given above.
