Division of Grams and Kilograms

Division of grams and kilograms by whole numbers

Divide 18 kg 360 g by 6.

In groups of four:

Arrange the division in a vertical form.
Divide 18 kg by 6.

$\begin{matrix} kg g \\ 6 18 kg 360 g \end{matrix}$

Divide 360 g by 6.
Discuss the results in your group and share with other groups.

Example 8

Syombua had 50 kg 520 g of peas. She packed the peas in 5 packets of equal mass. What was the mass of each packet?

Total mass of peas:
50 kg 520 g
Mass of each packet:
50 kg 520 g ÷ 5

Mass of each packet was 10 kg 104 g

Example 9

Work out 36 kg 470 g ÷ 7

36 kg 470 g ÷ 7 = 5 kg 210 g

Exercise M

$\begin{matrix} kg g \\ 8 32 kg 480 g \end{matrix}$
$\begin{matrix} kg g \\ 9 27 kg 810 g \end{matrix}$
$\begin{matrix} kg g \\ 5 156 kg 2 500 g \end{matrix}$

$\begin{matrix} kg g \\ 6 27 kg 600 g \end{matrix}$
$\begin{matrix} kg g \\ 7 67 kg 270 g \end{matrix}$
$\begin{matrix} kg g \\ 4 125 kg 224 g \end{matrix}$
