1.3/4 - 3/2 = 2.6,17 - 3/4 = 3.0,40 + 1/4 = 4.3/5 :0,2 = 5.16 2/3 % = 6.4 1/3 + 14 2/7 % = 7.6 1/4 : 0.3 = 8.3 2/3 x 1/4 = 9.3/5 : 2/7 :4/8 =

1. 3/4 - 3/2 = 3/4 - 6/4 = -3/4
2. 6,17 -3/4 = 617/100 - 3/4 = 542/100 atau 5,42
3.0,40 + 1/4 = 4/10 + 1/4 = 26/40
4.3/5:0,2 = 3/5 x 10/2 = 3
7. 6 1/4 : 0.3= 125/6
8. 3 2/3 x 1/4 = 11/12
9. 3/5:2/7:4/8= 21/5

semoga benar
