Division of kilometres and metres
Group Activity 9
In pairs: Nyoro walked 30 km 100 m in 7 days. He walked equal distances each day.
Find the distance he covered in a day.
- Set the question in division form.
- First divide km by 7. Write the quotient above 30 km.
- Multiply the quotient by 7 and write the answer below 30. Subtract the product from 30 km.
- Convert the result obtained in (3) into metres and add it to 100 m.
- Divide the result in (4) by 7. Write the quotient above 100.
- Discuss the results and share with other groups.
Example 8
a) Divide 75 km 370 m by 5
Therefore,
75 km 370 m ÷ 5 = 15 km 74 m
b) Divide 25 km 254 m by 3
Therefore,
25 km 254 m ÷ 3 = 8 km 418 m
Exercise K
K1
Work out in pairs:
K2
Work out:
- 95 km 365 m by 5
The result is km m. - 144 km 660 m by 12
The result is km m. - 42 km 228 m by 9
The result is km m. - 161 km 800 m by 20
The result is km m.
