Understanding the Fraction of 1.2
To determine the fraction of 1.2, you first need to understand that a fraction represents a part of a whole. The number 1.2 can be expressed as a fraction by recognizing it as 1.2/1. To eliminate the decimal, multiply both the numerator and denominator by 10, giving you 12/10. This fraction can be simplified by dividing both the numerator and denominator by 2, resulting in 6/5. Therefore, the fraction of 1.2 is 6/5, which can also be interpreted as one and two-fifths or 1.2 in decimal form.
The Basics of Fractions
Fractions are fundamental components in mathematics used to express parts of a whole. They consist of a numerator (the top part) and a denominator (the bottom part). In our case, we explored how to represent the decimal number 1.2 as a fraction through various mathematical operations.
Understanding Decimals and Fractions
Decimals can be converted to fractions easily by following a few steps. Understanding how to perform these conversions is essential for enhanced mathematical comprehension and application. Every decimal point can be transformed into a fraction through multiplication and simplification methods, an integral part of mathematical literacy.
Step-by-Step Conversion of 1.2 to a Fraction
- Start with the decimal: 1.2.
- Write it as a fraction over 1: 1.2/1.
- Eliminate the decimal by multiplying both numbers by 10: (1.2 × 10)/(1 × 10) = 12/10.
- Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 2: 12 ÷ 2 / 10 ÷ 2 = 6/5.
Through this process, you have successfully converted 1.2 into the fraction 6/5.
Types of Fractions
To better understand fractions, it’s important to know the types and their characteristics:
1. Proper Fractions
A proper fraction has a numerator smaller than the denominator (e.g., 3/5).
2. Improper Fractions
An improper fraction has a numerator greater than or equal to the denominator (e.g., 7/4 or 6/5).
3. Mixed Numbers
A mixed number combines a whole number and a proper fraction (e.g., 1 1/5).
