write the decimal form of the following rational numbers 1 25.
The correct answer and explanation is:
Correct Answer:
The decimal form of the rational number 1 25 is 26.0
Explanation:
A rational number is any number that can be written as a fraction or a whole number. The number 1 25 appears to be a mixed number, which typically means a combination of a whole number and a fraction. However, in this case, 1 25 actually just means 1 + 25, since no fraction is shown.
So, to find its decimal form:
1 + 25 = 26
Then, 26 as a decimal is written as 26.0.
In mathematics, whole numbers like 26 can always be written in decimal form by adding a decimal point followed by a zero. This does not change the value of the number. For example:
- 4 = 4.0
- 10 = 10.0
- 100 = 100.0
Decimals are used when more precision is needed, especially when dealing with measurements, money, or scientific data. Writing 26 as 26.0 is useful when comparing it with other decimal values or when placing it into a decimal system for calculation.
Additionally, rational numbers include integers, terminating decimals, and repeating decimals. The number 26.0 is a terminating decimal, which means the decimal representation ends after a finite number of digits. This confirms that 26.0 is rational.
When converting numbers to decimal form, it helps in operations such as addition, subtraction, multiplication, and division, especially in real-life contexts like budgeting, science experiments, and computer programming.
So, the decimal form of 1 25 is clearly and correctly written as 26.0.
