The concept of converting decimals to fractions is a fundamental aspect of mathematics, and it can be a bit tricky at times. In this article, we will explore the conversion of 7.2 as a fraction in a simplified explanation.
Understanding Decimals and Fractions
Before we dive into the conversion process, it's essential to understand the basics of decimals and fractions. Decimals are numbers with a point or comma separating the whole part from the fractional part. For example, 7.2 is a decimal number where 7 is the whole part, and 2 is the fractional part.
Fractions, on the other hand, represent a part of a whole as a ratio of two numbers. For instance, 3/4 is a fraction where 3 is the numerator, and 4 is the denominator.
Converting 7.2 to a Fraction
To convert 7.2 to a fraction, we need to follow a simple step-by-step process:
- Identify the decimal part: In this case, the decimal part is 0.2.
- Determine the place value: The decimal part 0.2 has a place value of tenths.
- Convert the decimal to a fraction: Since 0.2 has a place value of tenths, we can convert it to a fraction by writing it as 2/10.
- Simplify the fraction: The fraction 2/10 can be simplified by dividing both the numerator and denominator by 2, resulting in 1/5.
- Combine the whole part and fractional part: Now that we have the fractional part as 1/5, we can combine it with the whole part, which is 7.
The final result is:
7 1/5
Simplified Explanation
In simple terms, 7.2 as a fraction is equal to 7 and 1/5. This means that the decimal part 0.2 is equivalent to 1/5 of a whole.
