[1x(1 1/4x18 1/5)]+4-[(30-7 5/8)-(9 32/48+8 34/48)]=

Answer 1

(30-7 5/8(ułamek))-9 30/48+8 36/48=(29 8/8 - 7 5/8 ) - 17 66/48 =  22 3/8 - 17 66/48 = 22 18/48 - 18 18/48 = 4

 

4 3/5:(11 4/10-8 1/3+5/10= 23/5: (11 12/30 - 8 10/30 + 15/30) = 23/5: (3 2/30+15/30)=23/5: 107/30)=23/5 x 30/107 = 23/1 x 6/107 = 138/107=1 31/107

 

4 2/7x3 5/10-(8 5/6-4 4/6)x 6/5= 30/7 x 35/10 - 8 1/6 x 6/5 = 15- 49/6 x 6/5 =

15-49/5=15-9 1/5 = 14 5/5 - 9 1/5 = 5 4/5

 

6 3/4x1 3/7x 14/45x33 1/3:2= 27/4 x 3/7 x 14/45 x 100/3 ; 2 = 27/4 x 2/15 x100/3 : 2 = 2/15 x 27/4 x 100/3 :2 = 50:2=25
