Adding Weight

After adding the below weight, if the sum is $\mathrm{N} \mathrm{kg}$ and $\mathrm{M} \mathrm{g}$. Write the value of $\mathrm{N}$.

$\underline{\begin{array}{cccccccccc}& 3& 4& 3& \mathrm{kg}& & 4& 6& 7& \mathrm{g}\\ +& 1& 8& 6& \mathrm{kg}& & 3& 8& 9& \mathrm{g}\\ & & & & & & & & & \end{array}}$

Add the following:

If the required answer is of the form $A \mathrm{kg}$, then write is the value of $A$.

After adding the below weight, if the sum is $\mathrm{N} \mathrm{kg}$ and $\mathrm{M} \mathrm{g}$. Write the value of $\mathrm{N}$.

$\underline{\begin{array}{cccccccccc}& 3& 8& 7& \mathrm{kg}& & 4& 7& \mathrm{g}& \\ +& 1& 0& 6& \mathrm{kg}& & 3& 0& \mathrm{g}& \\ & & & & & & & & & \end{array}}$

Add the following:

If the required answer is of the form $A \mathrm{kg} B \mathrm{g}$, then write is the value of $A$.

Add or subtract as required.
$\begin{array}{ccccccccccc}& & & & & & & & & & \\ & 2& 4& 9& \mathrm{kg}& 6& 5& 0& \mathrm{g}& & \\ +& 1& 8& 0& \mathrm{kg}& 3& 8& 6& \mathrm{g}& & \\ & & & & & & & & & & \end{array}$

Add or subtract as required.
$\begin{array}{ccccccccccc}& & & & & & & & & & \\ & 3& 0& 0& \mathrm{kg}& 7& 5& 2& \mathrm{g}& & \\ +& & 2& 0& \mathrm{kg}& 1& 2& 0& \mathrm{g}& & \\ & & & & & & & & & & \end{array}$

Add or subtract as required.
$\begin{array}{ccccccccccc}& & & & & & & & & & \\ & 3& 4& 3& \mathrm{kg}& 4& 6& 7& \mathrm{g}& & \\ +& 1& 8& 6& \mathrm{kg}& 3& 8& 9& \mathrm{g}& & \\ & & & & & & & & & & \end{array}$
