1. 24+(-72) : (4×3)
= 24 - 72 : 12)
= 24 - (72 : 12)
= 24 - 6 = 18
OPTION = c.18

2. 128 : (-16)+ 80 × 2
= (128 : (-16)) + (80 × 2)
= -8 + 160
= 160 - 8 = 152
OPTION = b.152

3. 60 ÷ 12 × 2
= 5 × 2
= 10
OPTION = a.10

4. 3,45 =...
= 345 / 100 = 3 45/100
= 3 (45÷5) / (100÷5)
= 3 9/20
OPTION = b. 3 9/20
