Penjelasan dengan langkah-langkah:
6. 3 1/2 + 4 2/3 - 1 5/6
= (3+4-1) + ( 1/2 + 2/3 - 5/6)
= 6 + (3/6 + 4/6 - 5/6)
= 6 2/6 = 6 1/3
7. 2 3/4 + 26% - 0,152
= 2,750 + 0,260 - 0,152
= 2,858
8. 4,25 + 2,75 + 1,25 = 8,25 kg
9. 14 - (2,5 + 3 1/4 + 4 2/5)
= 14 - (2,5 + 3,25 + 4,4)
= 14 - 10,15
= 3,85 kg
10. 3/5 : 2 = 3/5 x 1/2 = 3/10
