1 1/2 ; 40% ; 0,3 ; 1/9

3b] 1 1/2 + 40% - 0,3 : 1/9
= 3/2 + 40/100 - 3/10 x 9/1
= 3/2 + 40/100 - 27/10
= 150/100 + 40/100 - 270/100
= 190/100 - 270/100 (dibalik)
= 80/100 >> 4/5

3c] 1 1/2 x 40% + 0,3 - 1/9
= 3/2 x 40/100 + 0,3 - 1/9
= 120/200 + 3/10 - 1/9
= 120/200 + 60/200 - 1/9
= 180/200 - 1/9
= 162/1800 - 200/1800 (dibalik bisa)
= 38/1800 >> 19/900

3d] 1 1/2 : 40% - 0,3 x 1/9
= 3/2 : 40/100 - 3/10 x 1/9
= 3/2 x 100/40 - 3/90
= 300/80 - 3/90
= 2700/720 - 24/720
= 2676/720 >> 223/60

3e] 1 1/2 + 40% x 0,3 : 1/9
= 3/2 + 40/100 x 3/10 : 1/9
= 3/2 + 120/1000 : 1/9
= 3/2 + 120/1000 x 9/1
= 3/2 + 1080/1000
= 1500/1000 + 1080/1000
= 2580/1000 >> 129/50

3f] 1 1/2 - 40% : 0,3 x 1/9
= 3/2 - 40/100 : 3/10 x 1/9
= 3/2 - 40/100 x 10/3 x 1/9
= 3/2 - 400/300 x 1/9
= 3/2 - 400/2700
= 4050/2700 - 400/2700
= 3650/2700 >> 73/54
