Soal 1 : 32/3 + 11/6=
1. 32/3 + 11/6 = 64/6 + 11/6 = 75/11 = 6 9/11
2. 3/5 + 5/8 = 24/40 + 25/40 = 49/40 = 1 9/40
3. 3/8 x 4/5 = 12/40 = 3/10
4. 21/3 x 31/2 = 651/6 = 108 3/6
5. 5/6 : 5/8 = 5/6 x 8/5 = 8/6 = 1 2/6 = 1 1/3
6. 21/4 : 11/2 = 21/4 x 2/11 = 21/22
7. 8,35 + 1,6 = 8 35/100 + 1 6/10 = 8 35/100 + 1 60/100 =9 95/100 =9,95
8. 12,3 + 9,25 = 12 3/10 + 9 25/100 = 12 30/100 + 9 25/100 = 21 55/100 = 21,55
9. 0,9 x 0,5 = 9/10 x 5/10 = 45/100 = 0,45
10. 16,5 : 0,5 = 16 5/10 x 10/5 = 16 50/50 = 17
