jika diketahui a=1/3,b=¾,dan c=2/5,maka tentukan nilai operasi berikut! a.aXbXc b.ab-ac c.(b-c)Xa d.2ab:c e.2/3e-1/2c

a. 1/3 x 3/4 x 2/5 = 6/60 = 1/10
b. 1/3 x 3/4 - 1/3 x 2/5 = 3/12 - 2/15 = 12/60 - 8/60 = 4/60 = 1/15
c. (3/4-2/5)x1/3 = (15/20-8/20)x1/3 = 7/20x1/3 = 7/60
d.2x(1/3x3/4):2/5 = 2x3/12 :2/5 = 3/6:2/5 = 3/6 x 5/2 = 15/12
