Question

Simplifique as expressões : No gabarito a primeira dá 137/8 e a segunda dá 163/529.

Answer 1

c) $\frac{215 \frac{9}{16}-208 \frac{3}{4}+ \frac{1}{2} }{0,0001:0,005}$

$\frac{\frac{3449}{16}-\frac{835}{4}+ \frac{1}{2} }{ \frac{1}{10000} : \frac{5}{1000} }$

$\frac{\frac{3449}{16}-\frac{3340}{16}+ \frac{8}{16} }{ \frac{1}{10000} . \frac{1000}{5} }$

$\frac{\frac{3449-3340+8}{16}}{ \frac{1}{10} . \frac{1}{5} }$

$\frac{\frac{117}{16}}{ \frac{1}{50} }$

$\frac{117}{16}.\frac{50}{1}$

$\frac{117}{8}.\frac{25}{1}$

$\frac{2925}{8}$


d) $\frac{(58 \frac{4}{15} -56 \frac{7}{26} ):0,8+2 \frac{1}{9} .0,225}{8 \frac{3}{4} . \frac{3}{5} }$

$\frac{(\frac{874}{15} -\frac{1463}{26} ): \frac{8}{10} +\frac{19}{9} . \frac{225}{1000} }{\frac{35}{4} . \frac{3}{5} }$

$\frac{(\frac{22724-21945}{390} ). \frac{10}{8} +\frac{19}{1} . \frac{25}{1000} }{\frac{7}{4} . \frac{3}{1} }$

$\frac{(\frac{779}{39} ). \frac{1}{8} +\frac{19}{1} . \frac{1}{40} }{\frac{7}{4} . \frac{3}{1} }$

$\frac{\frac{779}{312} +\frac{19}{40} }{\frac{21}{4} }$

$\frac{\frac{3895+741}{1560} }{\frac{21}{4} }$

$\frac{\frac{4636}{1560} }{\frac{21}{4} }$

$\frac{4636}{1560} .\frac{4}{21}$

$\frac{4636}{390} .\frac{1}{21}$

$\frac{2318}{195} .\frac{1}{21}$

$\frac{2318}{4095}$
