I personally would convert them to improper fractions, add them and then convert the result back to a mixed number.
However, if you want to add the parts separately, it would be better to add the fractions first as this could result in a carry of a whole number to add into the addition of the whole numbers.
eg 2 1/3 + 3 5/6
Adding fractions and whole numbers separately:
Fractions: 1/3 + 5/6 = 2/6 + 5/6 = 7/6 = 1 + 1/6 = 1/6 + (carry to the whole numbers)
Whole numbers: 2 + 3 + (carry) = 2 + 3 + 1 = 6
→ 2 1/3 + 3 5/6 = 6 1/6
Done as improper fractions:
2 1/3 + 3 5/6 = (2x3+1)/3 + (3x6+5)/6 = 7/3 + 23/6 = 14/6 + 23/6 = 37/6 = (6x6+1)/6 = 6 1/6
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
first u find a common denominator
When you have a common denominator, the 2 fractions can be added by simply adding the numerators togethr and keeping the denominator. It might be harder to visualise this process without first getting a common denominator, thus having it might allow you to have a more accurate answer.
The first step in finding the lowest common denominator of two fractions is to multiply the two denominators. Then you see if there are any smaller numbers that are divisible by both denominators.

The trick to adding fractions is three simple steps. First, make sure the bottom numbers (the denominators) are the same. Secondly, add the top numbers (the numerators), put the answer over the denominator. Finally, simplify the fraction if need be.
Whole numbers are rational numbers with a denominator of 1. The difference with general rational numbers is that the denominators are likely to be different and they must be made the same by converting the fractions into equivalent fractions with the same denominator before the addition can be done - by adding the numerators and keeping the denominator, and simplifying (if possible) the result. With whole numbers the denominators are already the same (as 1) and so the addition can be done straight away.
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).

The first step to take is find the lowest common denominator of the fractions which can be done by finding the lowest common multiple of the numbers.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
you must make the fractions equivalent and with the same denomenator
yes you do, first you make the denominators the same, then you add the numerator after that you can regroup any "extras" into those whole numbers.
