Explicación paso a paso:

Resolver:

2 + [3/5 - (3/8 +2/9)+ 7/8]​

Resolvamos:

2 + [3/5 - (3/8 +2/9)+ 7/8]​

2 + [3/5 - (43/72)+ 7/8]​

2 + [3/5 - 43/72 + 7/8]​

2 + [1/360 + 7/8]​

2 + [79/90]​

259/90

Operaciones usadas:

$\frac{3}{8} + \frac{2}{9}=\frac{(3)(9) + (2)(8) }{72} =\frac{27+16}{72} =\frac{43}{72}$

$\frac{3}{5} - \frac{43}{72}=\frac{(3)(72) - (43)(5) }{360} =\frac{216-215}{360} =\frac{1}{360}$

$\frac{1}{360} + \frac{7}{8}=\frac{(1)(1) + (7)(45) }{360} =\frac{1+315}{360} =\frac{316}{360} =\frac{79}{90}$

$\frac{2}{1} + \frac{79}{90}=\frac{(2)(90) + (79)(1) }{90} =\frac{180+79}{90} =\frac{259}{90}$

Por lo tanto, el valor de la operación es 259/90
