Question

calculati diferenta dintre modul 4/3 si opusul nr 1,6

Answer 1

1,6 = $\frac{16}{10} = \frac{8}{5}$ 

opsulu lui   $\frac{8}{5}= - \frac{8}{5}$

|$\frac{4}{3}$| $- ( -\frac{8}{5}) =$ = |$\frac{4}{3}$|+ $\frac{8}{5} =$ = $\frac{4}{3}+ \frac{8}{5} = \frac{20}{15} + \frac{24}{15} = \frac{44}{15}$
