The sum of two like fractions is 11 20 and their difference is 3 20Find the fractions?
Short answer: 7/20 and 4/20
Long answer:
We know that like fractions have the same denominator so we know that the denominator for both is 20, which is the same as your equations, so we can pretty much ignore them for right now. Now we need to figure out the numerators using a little algebra. Here's what we know:
x + y = 11
x - y = 3
We can simplify the second equation to
x = 3 + y
We can now plug that into the first equation to get
3 + y + y = 11
And now we simplify:
3 + y + y = 11
3 + 2y = 11
2y = 8
y = 4
So now we know one numerator is 4. We can plug that into x = 3 + y to find out what the second numerator is. x = 3 + 4. So the second numerator is 7. We add the denominators to get
4/20 and 7/20

What is true about the numerator of two like fractions with a sum of 1?
They add to the denominator!
How can you tell whether the sum of two fractions with a common denominator is greater than 1 less than 1 or equal to?
To determine whether the sum of two fractions with a common denominator is greater than, less than, or equal to 1, you need to add the numerators of the fractions together and compare the result to the common denominator. If the sum of the numerators is greater than the denominator, the sum of the fractions will be greater than 1. If the sum of the numerators is less than the denominator, the sum of the fractions will be less than 1. If the sum of the numerators is equal to the denominator, the sum of the fractions will be equal to 1.
When does the sum of two fractions equal one?
The sum of two fractions will be equal to one when the numerator and the denominator of their sum are the same. Example: 1/3 + 2/3 = 3/3 or 1
What is a good comparison of the estimated sum and actual sum of fractions?
A good comparison is the percentage error.
When does the sum of two fractions equal 1?

Find the sum of fractions?
If I had some fractions, I might. But since I don't, I won't.
