I need someone to check and go over my answers to make sure they are correct and if not could you go over them with my on why and how to solve correctly??
Thank you much appreciated..
Add.
-4/5 + (9/20) = 5/25
1 + (-2) + 3 + (-4) = 10
5/3 + (-4/3) + 5/3 = 6/3
No, No, and the last, yes.
on the first, change all terms to have 20 in the denominator.
On the second, see my other post.
-4/5 + (9/20) =
Note that the common denominator is 20, not 25.
-(16/20) + (9/20) = -(7/20)
_______________________________
1 + (-2) + 3 + (-4) =
I don't see how you can get 10 from this problem.
4 + (-6) = ?

Your last problem is right -- but can be reduced to 2.
I did not read or do it carefully
so I reworked these problems and my answers are:
1. -7/20
2. -2
and the third one is 6/3 = 2
Of course! I'd be happy to go over your answers with you. Let's take a look at each problem step-by-step:
1. -4/5 + (9/20) = 5/25
To solve this addition problem, we need to find a common denominator for both fractions. The smallest number that both 5 and 20 can divide into is 20. We then need to multiply the numerator and denominator of each fraction by the appropriate factor to have a common denominator of 20.
-4/5 needs to be multiplied by 4/4 to get -16/20.
9/20 remains the same.
Now, we can add the fractions by adding the numerators while keeping the denominators the same:
-16/20 + 9/20 = -7/20
Therefore, the correct answer is -7/20, not 5/25.
2. 1 + (-2) + 3 + (-4) = 10
In this equation, we are adding a combination of positive and negative numbers. We simply need to add each number together while keeping track of the positive and negative signs.
1 + (-2) + 3 + (-4) can be rewritten as 1 - 2 + 3 - 4.
Now, we can add these numbers step-by-step:
1 - 2 = -1
-1 + 3 = 2
2 - 4 = -2
Therefore, the correct answer is -2, not 10.
3. 5/3 + (-4/3) + 5/3 = 6/3
To add fractions, we need a common denominator. In this case, the denominator is already the same for all three fractions, which is 3.
Now, we can add the numerators while keeping the denominator the same:
5/3 + (-4/3) + 5/3 = (5 - 4 + 5)/3 = 6/3
The answer 6/3 is equivalent to 2, so both answers are correct.
In summary:
-4/5 + (9/20) = -7/20
1 + (-2) + 3 + (-4) = -2
5/3 + (-4/3) + 5/3 = 2
I hope this helps clarify the correct answers and the steps to solve each problem!
