How to add fractions having similar numerators but different denominators?
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
Why is it inaccurate to simplify add the numerators if two fractions with unlike denominator?
Because that is not how addition of fractions is defined.
When asked to find the sum of two mixed numbers with different denominators you should before you add.?
convert both to numbers with lowest common denominator then add
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators

How do you add or subtract dissimilar fractions?
You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Why do fractions need a common denominator when adding subtracting?
In order to add or subtract one fraction from another, they must have a common denominator, or the same denominator. That's because it's impossible to add two fractions that have a different number of parts.
How do you add two fractions with the same denominator?
numerators you add, denominators you leave it the same
How do you find the sum of two mixed numbers?
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
Why do you need a common denominator?
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
Why is it inaccurate to simplify add the numerators if two fractions with unlike denominator?
Because that is not how addition of fractions is defined.
When asked to find the sum of two mixed numbers with different denominators you should before you add.?

Adding unlike fractions?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
How do subtract two fractions with different denominator?
First find the lowest common denominator and then adjust the fractions accordingly before subtracting the numerators
What is true about the numerator of two like fractions with a sum of 1?
They add to the denominator!
