5.
Write 4 1/2 as a decimal.
Explanation
The decimal representation of a mixed number can be found by dividing the whole number part by the denominator and adding the resulting quotient to the fractional part. In this case, the whole number part is 4 and the fractional part is 1/2. Dividing 4 by 2 gives us 2, and adding this to the fractional part gives us 2 + 1/2 = 2.5. Therefore, the decimal representation of 4 1/2 is 4.5.
6.
What is 3 2/5 written as a decimal?
Explanation
The given number, 3 2/5, represents 3 whole units and 2/5 of another unit. To convert this mixed number to a decimal, we add the whole number part (3) to the fraction part (2/5). Since the fraction has a denominator of 5, we divide the numerator (2) by the denominator (5) to get 0.4. Adding this to the whole number part, we get 3.4 as the decimal representation of 3 2/5.

A repeating decimal goes on forever and never stops.
Correct Answer
A. True
Explanation
A repeating decimal is a decimal representation of a number that has a repeating pattern of digits after the decimal point. This pattern can be a single digit or a group of digits that repeats infinitely. For example, the fraction 1/3 can be expressed as the repeating decimal 0.333..., where the digit 3 repeats infinitely.
