Chapter 0, Problem 13P

To determine

To find: the difference of the given numbers

Answer to Problem 13P

The required difference is $5.3-4.7=0.6$

Explanation of Solution

Given:

  $5.3-4.7$

Calculation:

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

Since, both have 1 digit after decimal, proceed.

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

  $\begin{array}{l}\begin{array}{l}53\\ \underset{\_}{-47}\end{array}\hfill \\ 06\hfill \end{array}$

Now, decimal point is placed after 1 digit from end as it was placed so in each entry for addition

Thus, difference of numbers $5.3-4.7$ is 0.6

Hence, the required difference is $5.3-4.7=0.6$

Conclusion:

Hence, the required difference is $5.3-4.7=0.6$
