Since we are adding fractions, the denominators must be the same. Therefore, we need to find a number that is a multiple of 82 and 13. The least common multiple of 82 and 13 is 82, so the missing denominator should be 82.
Therefore, the correct answer is 82.
Which of the following numbers should replace the missing denominator in order to add the fractions? 25/82 + 13/? (1 point)
