D. 5 3/4 + 4 1/6 - 3 3/7 = 6 41/84
E. 15 5/8 + 8 2/9 - 5 1/12 = 18 55/72

Answer 2

Caranya dengan pecahan campuran diubah dulu menjadi pecahan biasa,maka;
a.5/2 + 10/3 - 9/4 = 30/12+40/12-27/12= 43/12 = 3 7/12
b.39/5 -25/6 + 21/10 = 234/30 - 125/30 + 63/30 = 172/30 = 5 12/30 = 5 2/5
c.38/3 - 65/9+2/1 = 114/9 -65/9 + 18/9 = 67/9 = 7 4/9
d.23/4 +25/6 - 24/7 = 483/84 + 350/84 - 288/84 = 544/84 = 6 40/84 = 6 10/21
e.120/80 +74/9 - 61/12 =1080/72 + 592/72 - 366/72 = 1306/72=18 10/72 = 18 5/36
