I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
You divide the numerator by the denominator.

For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.

the most important thing is to change the denominators so u can make common denominators
Determine the lowest common denominator. Multiply the numerator and denominator of each fraction by a number that will result in the denominator becoming the LCD. The purpose for multiplying both the numerator and denominator is that any number divided by itself = 1, and when you multiply something by 1, you don't change it. When subtracting two fractions with the same denominators, the first numerator minus the second numerator equals the numerator of the result, and the result has the same denominator (the LCD). Simplify.
Divide the numerator by the denominator
You divide the numerator by the denominator.
you do what makes sense given the numbers, if the fractions work out beautifully, you can just leave them as mixed numbers, otherwise it's best to keep them as improper fractions
To change fractions into decimals divide the numerator by the denominator as for example 3/4 = 0.75
Divide the denominator into the numerator.
Mixed fractions can't become proper fractions. Mixed fractions are greater than one. You can, however, change a mixed number into an IMPROPER fraction by multiplying the whole number by the denominator and adding the numerator to become the new numerator over the original denominator, for example: 2 3/4 = (2×4+3)/4 = 11/4
