Question

(-16/5+1/3-5/2).(-1/2):(3/8)

Answer 1

$(\frac{-16}{5} + \frac{1}{3} - \frac{5}{2} )( \frac{-1}{2}: \frac{3}{8} )$

$( \frac{-48}{15} + \frac{5}{15} - \frac{5}{2} )( \frac{-1}{2}. \frac{8}{3} )$

$( \frac{-43.2}{30} - \frac{75}{30} )( \frac{-8}{6} )$

$( \frac{-86-75}{30} )( \frac{-4}{3} )$

$(\frac{-161}{30} )( \frac{-4}{3} )= \frac{644}{90} = \frac{322}{45}$

Answer 2

Olá Joao

-16/5 + 1/3 - 5/2

mmc(2,3,5) = 30

-96/30 + 10/30 - 75/30 = -161/30 

(-161/30)*(-1/2) = 161/60 

(161/60)/(3/8) = (161/60)*(8/3) = 1288/180 = 322/45
