To find: the difference of the given numbers

Answer to Problem 17P

The required difference is $569.43-97.1=472.33$

Explanation of Solution

Given:

  $569.43-97.1$

Calculation:

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

Thus, 0 is annexed to 97.1 after decimal to write it as 97.10

Then subtraction is performed in normal way. Forget about decimal point

  $\begin{array}{l}56943\\ \underset{\_}{-9710}\\ 47233\end{array}$

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

Thus, difference of numbers $569.43-97.1$ is 472.33

Hence, the required difference is $569.43-97.1=472.33$

Conclusion:

Hence, the required difference is $569.43-97.1=472.33$
