Question

Вычислите пожалуйста!!!!

Answer 1

1+2)1/2+5/6-7/9=(9+15+14)/18=38/18=19/9
3)19/9:5/3=(19×3)/(9×5)=57/45=1 4/15
4)15:2,4=150/24=25/4=6(1/4)
5)6(1/4)-6(1/36)=(9-1)/36=8/36=4/9
6)2,75=2(9/12).........2/3=8/12
2(9/12)-8/12=2(1/12)
7)2(1/12)×1,2=(25×12)/(12×10)=2,5
8)7/30+5/12=(14+25)/60=13/20=0,65
9)0,65:0,13=65:13=5
10) 1(4/15) 2,5 6(1/3)+1(1/9) 67
............ + ............... =....................... = ......... = 3,35
4/9 5 20/9 20
11)3,35:0,125=3350/125=154/5=30,8
