When adding fractions, we only add the numerators because the fractions must have a common denominator to represent the same whole. The denominator indicates how many equal parts the whole is divided into, so when the denominators are the same, we can simply combine the parts represented by the numerators. This allows us to express the total number of parts while keeping the same size of the whole. Thus, the formula becomes (\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}).
What else can I help you with?
How do you add and subtract like denominator?
You add or subtract only the numerators
To add and subtract fractions less than 1 you add or subtract only the what?
Numerators
To find the sum of two fractions with the same denominator you just have to add the?
Numerators
If the denominators are different do you add them?
No. Convert them to like denominators and add the numerators.
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
How do you add and subtract like denominator?
You add or subtract only the numerators
To add and subtract fractions less than 1 you add or subtract only the what?
Numerators
Do you add the denominator?
When adding like fractions, only the numerators are added.
How do add factions with the same denominator?
You first add the numerators then take the denominator to the bottom of the sum of the numerators.
To find the sum of two fractions with the same denominator you just have to add the?
Numerators
How do you Add rational expressions with common denominators and binomial numerators?
If the denominator is the same, you just add the numerators - just as with plain numbers.
When you add or subtract fractions with the same denominators what happens to the denominator in your answer?
It stays the same. Only the numerators change.
If the denominators are different do you add them?
No. Convert them to like denominators and add the numerators.
Does adding numerators and denominators work in fraction addition?
To add fractions, you cannot simply add the numberators and add the denominators. To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.
To get the answer of a rational expression when you have the same denominator what do you do?
add numerators
Why do you need a common denominator when you add fractions?
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.
Why will the answer always be one when two numerators add up to the same number as two like denominators?
Yes because the numerators add up to equal a whole number which is 1
