What is the sum of two fractions?
convert the fractions so the denominators are the same if they aren't already. then add the numerators, but keep the denominator the same.
To find the sum of two fractions with the same denominator you just have to add 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.
What are the two fractions when you add them together equal 1?
There are an infinite number of correct answers.The two fractions areany number/any denominatorandthe same denominator minus the first number/the same denominator
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 are equivalent fractions important when adding and subtracting fractions?
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
A denominator that is the same in two or more fractions?
A "common denominator"
What are compatible numbers for fractions?
I am not entirely sure what you mean, but if you need to add, subtract, or compare two fractions, they need to have the same denominator.
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.
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
When two or more fractions have the same denominator it is called what?
Common denominator
