Chapter 0, Problem 15P

To determine

To find: the difference of the given numbers

Answer to Problem 15P

Hence, the required difference is $851.79-570.85=280.94$

Explanation of Solution

Given:

  $851.79-570.85$

Calculation:

Decimal subtraction is like any other subtraction but it should be ensured that digits afterdecimal are same in both.

Since, both have 2 digits after decimal, proceed

Then subtraction/difference is performed in normal way, forgetting about decimal point

  $\begin{array}{rr}\hfill & \hfill 85179\\ \hfill & \hfill \underset{\_}{-57085}\\ \hfill & \hfill 28094\end{array}$

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

Thus, difference of numbers 851.79-570.85 is 280.94

Hence, the required difference is $851.79-570.85=280.94$

Conclusion:

Hence, the required difference is $851.79-570.85=280.94$
