In fractions, you can NEVER add or subtract
The answer to an addition is called the sum. Fractions and other numbers.
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 .
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.
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.
subtracting fractions
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.
numerators you add, denominators you leave it the same
They are equivalent fractions
Because that is not how addition of fractions is defined.
