Yes providing you change the fractions into decimals or change the decimals into fractions
By finding the lowest common multiple of the fractions with different denomiators that need to be added or subtracted
It is best to convert the mixed fraction to an improper fraction. They are then added together in the same way as proper fractions are added together.
Mixed numbers can be converted to improper fractions. Improper fractions can be added the same way proper fractions are.
That simply means that the fractions have different denominators. Such fractions cannot be directly added, subtracted, or compared; you have to convert them to a common denominator first.
Unlike fractions have denominators that are unequal, and therefore cannot be added or subtracted. If two fractions need to be added or subtracted they must first be converted to like fractions.
We can only add or subtract fractions if they have the same denominators

like, common denominator
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.

The hcf is useful in reducing fractions to their lowest terms and the lcm is useful in finding the lowest common denominator of fractions that have different denominators that need to be added or subtracted.
Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).
