1) 4 lusin + 4 buah
= (4 × 12) + 4
= 36 + 4
= 40 buah

2) 1 gros + 7 lusin
= (1 × 12) + 7 lusin
= 12 + 7
= 19 lusin

3) 36 lusin + 144 buah
= (36 ÷ 12) + (144 ÷ 144)
= 3 + 1
= 4 gross

4) 2.000 lembar + 100 rim
= (2.000 ÷ 500) + 100
= 4 + 100
= 104 rim

5) 7 rim + 80 lembar
= (7 × 500) + 80
= 3.500 + 80
= 3.580 lembar

1. 48 buah + 4 buah = 52 buah
2. 12 lusin + 7 lusin =19 lusin
3. 3 gros + 1 gros = 4 gros
4. 4 rim + 100 rim = 104 rim
5. 3500 lembar + 80 lembar = 4.300 lembar
