selesaikan operasi hitung beikut a sampai j

ok la.... hahahaah......

a). 3 3/4 + 2 1/6 = 15/4 + 13/6 = 45/12 + 26/12 = 71/12
b). 5 2/9 - 3 1/2 = 47/9 - 7/2 = 94/18 - 63/18 = 31/18
c). 2 5/6 X 1 1/3 = 17/6 X 4/3 = 68/18
d). 1 1/5: 1/4 = 6/5 X 4/1 = 24/5
e). 2 X 4 3/8 - 5 3/4 = 2 X (35/8 - 23/4)
= 2 X (35/8 - 46/8)
= 2 X -1.375
= -2,75
f). 2,307 + 7,4296 = 9,7366
g). 12,625 - 5,1235 = 7,5015
h). 4,75 X 10,04 = 47,69
i). 39, 75: 2,65 = 0,8335081
j). 10,125 - (34, 125: 6,5) =
10,125 - 5,25 = 4,875

semoga membantu dan bermanfaat :)
