Chapter 0, Problem 12P

To determine

To find: the sum of the given numbers

Answer to Problem 12P

Hence, the required sum is $4865.7+705.76=5571.46$

Explanation of Solution

Given:

  $4865.7+705.76$

Calculation:

Decimal addition is like any other addition but it should be ensured that digits after decimal aresame in both.

Thus, 0 is annexed to 4865.7 so as to make it 4865.70

Then addition is performed in normal way, forget about decimal point

  $\begin{array}{l}48657+70576\hfill \\ =557146\hfill \end{array}$

Now, decimal point is placed after 2 digits from end as it was placed so in each entry foraddition.

Thus, addition of numbers $4865.7+705.76$ is 5571.46

Hence, the required sum is $4865.7+705.76=5571.46$

Conclusion:

Hence, the required sum is $4865.7+705.76=5571.46$
