What are the common data types used for numbers?*1 pointStrings, charsIntegers, floatsIntegers, stringsFloats, chars

To determine the common data types used for numbers, let's analyze the options provided:

1. Strings, chars - Strings are typically used for text data, while chars are single character data types. Neither is used specifically for numbers.

2. Integers, floats - This combination is commonly used for numerical data. Integers are whole numbers, and floats are numbers that can contain decimal points.

3. Integers, strings - While integers are numerical, strings are not a numerical data type.

4. Floats, chars - Floats are numerical, but chars, being single characters, do not categorize as numbers.

Conclusion

The most appropriate option that specifically describes the common data types used for numbers is Integers, floats. Therefore, if I were to select from the options presented, I would choose this pair as it accurately represents the typical data types employed for numerical values in programming.
