First Method:

Round \frac{3}{5} to the closest integer, which is 1.

Round \frac{3}{4} to the closest integer, which is also 1.

So 1 + 1 = 2.

Answer for method 1: 2

Second Method:

\frac{3}{5} + \frac{3}{4} = \frac{3*4}{5*4} + \frac{3*5}{4*5}  = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}

\frac{27}{20} is around 1

Answer for method 2: 1

The closest answer is 1.
