Question

va rog ajutati imi trebuie urgent​

Answer 1

(326-32/90 + 506-50/90)×3/25=x/28

(294/90 + 456/90)×3/25=x/28

750/90×3/25=x/28

(simplificam 750 si 90 cu 3)

250/30/25=x/28

250/30 : 25=x/28

scriem prima fractie inmultita cu a 2 a inversata

250/30×1/25=x/28

simplificam 250 si 25 cu 25

10/30=x/28

x=10×28/30

x=280/30

simplificam cu 10 fractia

x=28/3
