Answer 1

Respuesta:

Explicación paso a paso:

1)

$\frac{4}{3}-\frac{5}{6}+\frac{1}{2}\\\\\\=\frac{8}{6}-\frac{5}{6}+\frac{3}{6}\\\\\\=\frac{8-5+3}{6}\\\\\\=\frac{6}{6}\\\\\\=1$

---------------------------------

2)

$\frac{10}{7}+\frac{5}{8}-\frac{3}{2}\\\\\\=\frac{80}{56}+\frac{35}{56}-\frac{84}{56}\\\\\\=\frac{80+35-84}{56}\\\\\\=\frac{31}{56}$

en decimal ( 0,55357......)

--------------------------------------

3)

$-\frac{5}{6}+\frac{7}{4}-\frac{8}{3}+\frac{5}{2}\\\\\\=-\frac{10}{12}+\frac{21}{12}-\frac{32}{12}+\frac{30}{12}\\\\\\=\frac{-10+21-32+30}{12}\\\\\\=\frac{9}{12}\\\\\\=\frac{3}{4}$

-------------------------------------

4)

$\frac{6}{5}+\frac{8}{3}-4\\\\\\=\frac{6}{5}+\frac{8}{3}+\frac{-4}{1}\\\\\\=\frac{18}{15}+\frac{40}{15}+\frac{-60}{15}\\\\\\=\frac{18+40-60}{15}\\\\\\=\frac{-2}{15}\\\\\\=-\frac{2}{15}$
