Tolong jawab soal bagian 1, a sampai f

a) 1/8 + 3/4 = 1/8 + 6/8 = 7/8
b) 3/5 + 1/2 = 6/10 + 5/10 = 11/10 = 1 1/10
c) 8/9 - 2/3 = 8/9 - 6/9 = 2/9
d) 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2
e) 2/6 + 1/4 + 1/3 = 4/12 + 3/12 + 4/12 = 11/12
f) 9/10 - 3/5 - 1/4 = 18/20 - 12/20 - 5/20 = 1/20

a. 1/8+3/4= 1/8+6/8= 7/8
b. 3/5+1/2= 6/10+5/10= 11/10= 1 1/10
c. 8/9-2/3= 8/9+6/9= 2/9
d. 5/6-1/3= 5/6-2/6= 3/6= 1/2
e. 2/6+1/4+1/3= 4/12+3/12+4/12= 11/12
f. 9/10-3/5-1/4= 18/20-12/20-5/20 = 1/20
