Реши уравнение дроби 1) 3 2/45х+1 7/30х=6 1/9 2) (8 2/5/x+3 5/9)/4 1/6=1 1/3

3 2/45х+1 7/30х=6 1/9

(3*45+2)/45x+(1*30+7)/30x=(6*9+1)/9

137x/45+37x/30=55/9                 |*90

274x+111x=550

385x=550

x=550/385=110/77=10/7

(8 2/5/x+3 5/9)/4 1/6=1 1/3

(42/(5x)+32/9)/ (25/6)=4/3

42/(5x)+32/9=4/3*25/6

42/(5x)=50/9-32/9

42/(5x)=2

5x=42/2=21

x=21/5=4.2
