Question

Va rog mult! Exercițiul 3 punctul d!

Answer 1

d)
$\frac{4 \times 5}{6} - \frac{4 \times 1}{2} + \frac{8 \times 1}{2 \times 10} = \frac{20}{6} - \frac{4}{2} + \frac{8}{20}$
simplifici
$\frac{10}{3} - 2 + \frac{4}{10}$
aduci la acelasi numitor adica 30
$\frac{100 - 60 + 120}{30} = \frac{160}{30}$
