Question

2/3+5/2+7/2= va rog am mare nevoie de acest ex dau coroana

Answer 1

$\frac{2}{3}$+$\frac{5}{2}$+$\frac{7}{2}$=

²$\frac{2}{3}$+³$\frac{5}{2}$+³$\frac{7}{2}$=

$\frac{4}{6}$+ $\frac{15}{6}$+$\frac{21}{6}$=

$\frac{40}{6}$

Unde am pus 2 si 3 in fata, trebuie amplificat cu acele numere.

Answer 2

$\frac{2}{3} + \frac{5}{2} + \frac{7}{2} = \frac{20}{3} = 6 \frac{2}{3} = 6.666667$
Rezultatul rezulta din:

$a) \: \frac{2}{3} + \frac{5}{2} = \frac{2 \times 2}{3 \times 2} + \frac{5 \times 3}{2 \times 3} = \frac{4}{6} + \frac{15}{6} = \frac{4 + 15}{6} = \frac{19}{6}$

si adaugam

$b) \: \frac{19}{6} + \frac{7}{2} = \frac{19}{6} + \frac{7 \times 3}{2 \times 3} = \frac{19}{6} + \frac{21}{6} = \frac{19 + 21}{6} = \frac{40}{6} = \frac{20}{3}$
Sper ca te-am ajutat!!!
