Chapter 0, Problem 11P

To determine

To find: the sum of the given numbers

Answer to Problem 11P

Hence, the required sum is $257.76+345.487=603.247$

Explanation of Solution

Given:

  $257.76+345.487$

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 257.76 so as to make it 257.760

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

  $\begin{array}{l}257760+345487\hfill \\ =603247\hfill \end{array}$

Now, decimal point is placed after 3 digits from end as it was placed so in each entry foraddition.

Thus, addition of numbers $257.76+345.487$ is 603.247

Hence, the required sum is $257.76+345.487=603.247$

Conclusion:

Hence, the required sum is $257.76+345.487=603.247$
