just add their numerators.
For example 3/101+11/101 have the same denominator.
Now add 3+11=14 AND the answer is 14/101
By finding their common denominator & adding the top numbers of-the fractions. : )
To add two rational expressions with the same denominator, you simply add the numerators together while keeping the denominator unchanged. The result is a new rational expression represented as (\frac{a + b}{c}), where (a) and (b) are the numerators of the original expressions, and (c) is the common denominator. Make sure to simplify the resulting expression if possible.
To add rational numbers, you can use the algorithm of finding a common denominator. First, identify the least common denominator (LCD) of the fractions involved. Then, convert each fraction to an equivalent fraction with the LCD, add the numerators together, and simplify the resulting fraction if necessary. This process ensures that you accurately combine the rational numbers.
multiply the denominator by the whole number, then add the numerator, the denominator is the same as the mixed numbers denominator
You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.
If the denominator is the same, you just add the numerators - just as with plain numbers.
add numerators
You add the numerators and put over the denominator.

You re-scale them so that the denominators are the same.
You multiply the denominator by the whole number the add the numerator and you keep the denominator the same.
When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.
Yes, you can.
Yes you have to add with the same denominator. when ever you do fractions they have to have the same denominator no matter what. So thats a yes
