15+56\dfrac{1}{5} + \dfrac{5}{6}
15+56\dfrac{1}{5} + \dfrac{5}{6}
Since these fractions have different denominators, we need to find the least common multiple of the denominators
The least common multiple of 5 and 6 is 30, so we need to multiply to make each of the denominators = 30
15∗66=630\dfrac{1}{5} * \dfrac{6}{6} = \dfrac{6}{30}
56∗55=2530\dfrac{5}{6} * \dfrac{5}{5} = \dfrac{25}{30}
Since these fractions have the same denominator, we can just add the numerators
630+2530=3130\dfrac{6}{30} + \dfrac{25}{30} = \dfrac{31}{30}
Because 3130\dfrac{31}{30} is an improper fraction (the numerator is greater than the denominator), we need to convert it to a mixed number
3130=1130\dfrac{31}{30} = 1\dfrac{1}{30}
