Question

el procedimiento de la siguiente operacion combinada:
(3.12-0.13)/2.3+4*(3+2.1*3.2)

Answer 1

$(3,12 - 0,13) : 2,3 + 4*(3+2,1*3,2) = \\ \\ (\frac{312}{100} - \frac{13}{100}) : \frac{23}{10}+ 4*(3+ \frac{21}{10}* \frac{32}{10})= \\ \\ (\frac{299}{100}) : \frac{23}{10}+ 4*(3+ \frac{672}{100})= \\ \\ \frac{13}{10}+ 4*\frac{243}{25}= \\ \\ \frac{13}{10}+\frac{972}{25}= \\ \\ \frac{130}{100}+\frac{3888}{100}= \boxed{ \frac{4018}{100}}$

Espero que te sirva, salu2!!!!
