Hola(｡•̀ᴗ-)✧

$2 \frac{11}{20}$

Explicación paso a paso:

Parte 1:

$\frac{3}{5} + \frac{1}{2} = \frac{2 \times 3 + 5 \times 1}{10} = \frac{11}{10} = 1 \frac{1}{10}$

Parte 2:

$1 \frac{1}{10} + \frac{7}{10} = \frac{11}{10} + \frac{7}{10} = \frac{11 + 7}{10} = \frac{18}{10} = \frac{9.2}{5.2} = 1 \frac{4}{5}$

Parte 3:

$1 \frac{4}{5} + \frac{3}{4} = \frac{9}{5} + \frac{3}{4} = \frac{4 \times 9 + 5 \times 3}{20} = \frac{51}{20} =2 \frac{11}{20}$

Espero te sirva :3
