2. 1/2 + 2 2/3
= 1/2 + 8/3
(penyebutya disamakan Jadi 6)
= (1/2× 3/3) + (8/3×2/2)
= 3/6 + 16/6
= 19/6 = 3 1/6

3. 3/4 + 1 4/5
= 3/4 + 9/6
(penyebutya disamakan Jadi 12)
= (3/4×3/3) + (9/6×2/2)
= 9/12 + 18/12
= 27/12 = 2 3/12 = 2 1/4

4. 0,4+2/5+2 1/2
= 4/10 + 2/5 + 5/2
(penyebutya disamakan Jadi 10)
= 4/10 + 4/10 + 25/10
= 33/10 = 3 3/10

5. 0,8+1/5+1 3/4
= 8/10+1/5+7/4
(penyebutya disamakan Jadi 20)
= 16/20+4/20+35/20
= 55/20 = 2 15/20 = 2 3/4
