Answer 2

1)    ...............=130/19 * 1/5 * 1/13 * 54/7 * 19/36 * 1/6 * 28=
      (13*5*2*6*9*19*7*4) / (19*5*13*7*9*4*6)=2

2)    ..........=208/23 * (14 * 11/40 * 10/77) * 1/4 :(39/115 * 10/3)=208/23 * 1/2 * 1/4 : 26/23=208/23 * 1/8 * 23/26=(26*8*23)/(23*8*26)=1

3)   ..........=133/135 :(19/75 :(29/60 * 3 * 4/29)) * 144/7 * 1/24=133/135 :(19/75 : 1/5) * 6/7=133/135:19/15*6/7=133/135*15/19*6/7=(19*7*15*3*2)/(15*3*3*19*7)=2/3

4)    ......=(5/11 * 24/11):(3/50:11/10):5/44 * 1/32=120/121:(3/50 * 10/11) * 44/5 * 1/32=120/121 * 3/55 * 44/5 * 1/32=(5*3*8*3*4*11) / (121 * 5*11*5*8*4)=9/605

5.       .......................=0,4

1)   1 2/63 : 1/7 : 13=65/63 * 7 * 1/13=5/9
2)   2,75 : 5/9=2 3/4 * 9/5=11/4 * 9/5=99/20
3)   99/20 * 5/66=9/24=3/8
4)   3 : 3/8=3 * 8/3=8
5)   8*0,05=0,4
