What is true about the numerators of two like fractions with a sum of 1?
That their sum is always equal to the denominator.
How do you add three fractions with unlike denominators?
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
What do you notice when the denominators in two fractions are the same?
You can represent the two fractions with one fraction with a numerator equal to the sum of the two individual numerators (with sign) and a denominator equal to just one of the two denominators.
When you estimate the sum of 2 fractions the estimate is never a whole number?
The sum of two fractions will only be a whole number if the fractions have a common denominator. When the denominators are different, the sum will be a fraction with a different denominator, making it impossible to be a whole number. Thus, estimating the sum of two fractions will generally result in a fraction, not a whole number.
What three fractions using 10 as the denominator whose sum is1?
(1/10) + (3/10) + (6/10) = 1
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.

That their sum is always equal to the denominator.
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 are three fractions using 10 as a denominator and 1 as its sum?
I have no idea what the "sum" of a fraction means.
Rename two thirds and three fourths as fractions with 12 of the denominator then add the Renamed fractions write the sum as a mixed number?
Two thirds and three fourths can be renamed as fractions with 12 of the denominator as 8/12 and 9/12 respectively. The sum of the renamed fractions as a mixed number is 1 5/12.

They will sum to the denominator.

What three fractions have ten as the denominator whos sum is one?
Is this what you mean ? ===> (1/10) + (2/10) + (7/10) = 1
What three fractions using 10 as the denominator whose sum is1?
(1/10) + (3/10) + (6/10) = 1
What is the sum of two thirds and four ninths?
Only fractions with the same denominator can be added directly. Addition of such fractions can be achieved by adding their numerators to form the numerator of the sum, with the common denominator of the added fractions constituting the denominator of the sum. In this instance, 2/3 = 6/9, and 4/9 + 6/9 = 10/9.
