A mixed number is made up of two parts: an integer (whole) part and a fractional part.
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
Fractional exponents follow the same rules as integral exponents. Integral exponents are numbers raised to an integer power.
Move the decimal point 8 places to the right, adding zeroes as necessary: 254,000,000
No.
Integers include 0, the negative numbers without fractional parts, and the positive numbers without fractional parts. The "without fractional parts" part of the description implies that all of the integers are whole numbers. Therefore, if you are adding integers, you are adding whole numbers.
When adding two mixed numbers, it is not always necessary to rename the fractional sum, but it can make the calculation easier. Renaming the sum involves converting the mixed numbers to improper fractions, adding the fractions, and then simplifying the result back to a mixed number if needed. This process can help avoid dealing with larger denominators and make the addition more straightforward.
