12+712\dfrac{1}{2} + \dfrac{7}{12}
12+712\dfrac{1}{2} + \dfrac{7}{12}
Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 2 and 12 is 12, so we need to multiply to make each of the denominators = 12
12∗66=612\dfrac{1}{2} * \dfrac{6}{6} = \dfrac{6}{12}
712∗11=712\dfrac{7}{12} * \dfrac{1}{1} = \dfrac{7}{12}
Since these fractions have the same denominator, we can just add the numerators
612+712=1312\dfrac{6}{12} + \dfrac{7}{12} = \dfrac{13}{12}
Because 1312\dfrac{13}{12} is an improper fraction (the numerator is greater than the denominator), we need to convert it to a mixed number
1312=1112\dfrac{13}{12} = 1\dfrac{1}{12}
