add, with same and not the same denominator

• an improper fraction is when the numerator is bigger than the denominator
• when the fraction's denominator is the same, we only need to add the numerator and turn it into a mixed number
• solve 7/2 + 8/2 =?

  15/2, when turned to a mixed number, which is 2 divided by 15, is 7 1/2
• when a fraction's denominators aren't the same, the first step is to find the lcm by listing the multiples of the denominators and find the common factor
• the second step when the fraction's denominators aren't the same, after listing, we have to multiply the number we multiplied to get our denominator to our numerator and denominator
• the 3rd step when the fraction's denominator aren't the same, we have to add our multiplied numerators together, we simplify, after that, we turn it into a mixed number
• steps when the denominators are the same

  1. add the numerator
  2. look to simplify
  3. turn to a mixed number
• steps when the denominators aren't the same

  1. list the multiples of the denominators and find the common factor
  2. multiply the number we multiplied to get the common factor by our numerator and denominator
  3. add the numerators together
  4. look to simplify
  5. turn to a mixed number
