Answer 1

Respuesta:

a) 22/15

b) -19/10

c) 1/3

Explicación paso a paso:

a)

$(\frac{8}{3}+\frac{12}{15})-\frac{6}{3}$

$(\frac{40+12}{15})-\frac{6}{3}$

$\frac{52}{15}-\frac{6}{3}$

$\frac{52-30}{15}$

22/15

b)

$(\frac{-7}{4}+(-\frac{2}{5}))-(-\frac{1}{4})$

$(-\frac{7}{4}-\frac{2}{5})+\frac{1}{4}$

$\frac{-35-8}{20}+\frac{1}{4}$

$\frac{-43}{20}+\frac{1}{4}$

$\frac{-43+5}{20}$

-38/20

-19/10

c)

$(\frac{4}{3}+(-\frac{1}{9}))-\frac{24}{27}$

$(\frac{4}{3}-\frac{1}{9})-\frac{8}{9}$

$\frac{12-1}{9}-\frac{8}{9}$

$\frac{11}{9}-\frac{8}{9}$

3/9

1/3
