**70 kg 350
g ÷ 7 = 10 kg 50 g**

**(ii) 66 g 720 mg ÷ 6**

**66 g 720
mg ÷ 6 = 11 g 120 mg**

**Try this **

**Divide
the following:**

a. 7 kg 490 g ÷ 7 =** ****1kg 070g**

b. 35 kg 650 g ÷ 5 =** 7kg 130g**

c. 6 g 240 mg ÷ 4 =** 1g 560mg**

d. 150 g 750 mg ÷ 15 =** 10g 050mg**

__Example__

How
many packets of 3 kg groundnut cookies can be made from 75 kg of groundnut
