In order to sum two rational numbers, we should find their lowest common denominator. In this case, the two fractions are
4 3 ​
19 18 ​
so, their lowest common denominator is 4 ⋅ 19 = 76 . So, the sum of the two numbers becomes
4 3 ​ + 19 18 ​ = 76 3 ⋅ 19 + 18 ⋅ 4 ​ = 76 57 + 72 ​ = 76 129 ​ = 1.697..
So, this number is closer to 2.
