Answer 1

Respuesta:

1) a:-7/9 b:3/2

2)

Explicación paso a paso:

1)

a:  $\frac{-4}{5}$÷$\sqrt{\frac{16}{100} }-(-\frac{11}{9} )$

 $\frac{-4}{5}$÷  $\frac{4}{10} }+(\frac{11}{9} )$

$\frac{-4}{5}* \frac{10}{4}+\frac{11}{9}$

$-2+\frac{11}{9} =\frac{-7}{9}$

b: $[(\frac{5}{10})^{2}$÷$(1-\frac{8}{10})]*\frac{12}{10}$

$[\frac{25}{100}$÷$\frac{2}{10} ]*\frac{12}{10}$

$[\frac{25}{100}*\frac{10}{2} *\frac{12}{10}$

$\frac{150}{100} =\frac{3}{2}$

2)

B=$1-\frac{2-\sqrt{\frac{25}{100} } }{(\frac{6}{10})^{2} }$

$1-\frac{2-{\frac{5}{10} } }{(\frac{36}{100}) }\\1-\frac{{\frac{15}{10} } }{(\frac{36}{100}) }\\\\\frac{\frac{36}{100}-{\frac{15}{10} } }{(\frac{36}{100}) }\\\\\frac{{\frac{-114}{100} } }{(\frac{36}{100}) }\\\frac{-114}{36} =\frac{19}{6} \\3B/2=19/4$
