Textbook Question
Chapter 12, Problem 1A
Round 0.42538 to 2 decimal places.
Expert Solution & Answer
To determine
To round:
The given decimal number up to two places.
Answer to Problem 1A
Explanation of Solution
Given:
The expression is:
Calculation:
The digit following the second decimal place is 5.
If the digit is equal to or greater than 5 then, 1 is added to the preceding number.
Thus, add 1 to the number 2 and, drop the rest digits.
Hence, the decimal number up to two places is 0.43.
Conclusion:
The decimal value up to two places is
