In fractions, you can NEVER add or subtract
The answer to an addition is called the sum. Fractions and other numbers.
Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.
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.
There are an infinite number of different fractions between two fractions. If you want the one that's exactly in the middle, half-way between them, there's only one of those. It's called the "average" of the two fractions. Find it like this: -- Add the two fractions together. -- Divide the sum by 2 .
They are equivalent fractions
numerators you add, denominators you leave it the same
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.
Because that is not how addition of fractions is defined.
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
it stay the same when you subtract fractions and when you add fractions.
Add them together, then divide by 2.
add or subrition
Add them together, divide by 2.
Halfway between two fractions would be the average of the two fractions, so add the two fractions together and divide by two! Let's take 1/2 and 3/4 as an example. Add 1/2 (or 2/4) and 3/4 and you get 5/4. Now divide by two ( or multiply the bottom part by two) and your answer is 5/8!
They are equivalent fractions.
Fractions! Otherwise you don't have anything to add.
