The decimal 3.1 represents a number that is greater than a whole number. To better understand its composition in terms of whole numbers and fractional parts, we can express it as a mixed number, which combines a whole number and a proper fraction. Let's convert 3.1 into a mixed number to see how many whole parts there are and what fraction remains.
Answer: In mixed number form, 3.1 is written as 3 1/10
Explanation: To convert a decimal to a mixed number, separate the whole number from the fractional part. Here, 3.1 consists of a whole number, 3, and a fractional part, 0.1.
To convert the decimal 0.1 to a fraction, recognize that 0.1 is equivalent to 1/10.
Thus, 3.1 can be expressed as 3 1/10.
Whole number = 3
Fractional part = 0.1 = 1/10
So, 3.1 = 3 1/10
