25. 1 1/4
26. 19/24
27. 31/35
28. 23/72
29. 1/2
30. 10/21
Explanation:
1. Add the numerators(3 and 2) and copy the denominators, after that the result will 5/4 which is an improper fraction so you have to turn it into a mixed number.
How to turn an improper fraction into a mixed number?
Divide the numerator to the numerator
After that you can see that the result has a remainder so you
Make the quotient into the whole number, make the remainder the new numerator, and copy the denominator, then simplify if possible
2. Since the fraction are dissimilar you need to make it similar in order to add them, after you make them similar fractions you can add them then simplify if possible.
What is Dissimilar fraction?
These are fractions that don't have the same denominators
What is Similar fraction?
fractions that have the same denominators
How do you make a Dissimilar fraction into a Similar fraction?
Use the process LCD or Least Common Denominator and try to find out the LCD of the two denominators (The LCD of those denominators will become the new denominator), then divide the result to the denominator of the first fraction and multiply it to the numerator of the first fraction and the result will be the new numerator and the do the same with the second fraction after that you add/subtract the new fractions.
3. Since the fraction are dissimilar you need to make it similar in order to add them, after you make them similar fractions you can add them.
4. Since the fraction are dissimilar you need to make it similar in order to add them, after you make them similar fractions you can subtract them.
5. Since the fraction are similar you can straightly subtract them then simplify if possible.
6. Since the fraction are dissimilar you need to make it similar in order to subtract them after you make them similar fractions you can subtract them.
