Rationale
23.572
To find the sum of 6, 12.55, and 5.022, we perform the addition: 6 + 12.55 + 5.022 = 23.572. This calculation confirms that option B is the correct choice.
A) The sum of 6 + 12.55 + 5.022 is greater than 18.55. When we perform the addition, the total exceeds this value, making this option inaccurate. Therefore, option A does not reflect the correct sum.
B) This option correctly represents the total obtained by summing the numbers: 6 + 12.55 + 5.022 = 23.572. Each number contributes to the final result, confirming that this is the accurate answer.
C) The value 30.572 exceeds the actual sum of the three numbers. An addition of 6, 12.55, and 5.022 does not approach this figure, highlighting that option C is incorrect.
D) The total 16.575 is also below the actual sum of the three numbers. The addition of the given values leads to a result much higher than this option, making D an incorrect choice as well.
Conclusion
The correct sum of 6 + 12.55 + 5.022 is 23.572, as shown in option B. Each of the other options either underestimates or overestimates the total, emphasizing the importance of accurate arithmetic in obtaining the correct answer. This exercise demonstrates fundamental addition skills necessary for various practical applications.
