Answer 1

7/25+4/10= 14/50+20/50=34/50=17/25

13/18 + 5 /5 /12= 13/18+ 1/12= 26/36+ 3/36= 29 /36

7/18+2/15= 35/ 90+ 12/90= 47 /90

5/6+3/4= 10/12+ 9/12= 19/ 12

Answer 2

7 : 25+ 4: 10= 14: 50+20: 50= 34: 50= 17: 25

13: 18 + 5 :5 :12= 13:18+ 1:12= 26:36+ 3:36= 29 :36

7:18+2:15= 35: 90+ 12:90= 47 :90

5:6+3:4= 10:12+ 9: 12= 19: 12  (si aici ne oprim pt ca nu se mai poate impartii)
sper ca te-am ajutat ;-)
