Understanding the Concept of Converting Decimal Numbers to Fractions
Converting decimal numbers to fractions is a fundamental concept in mathematics. It involves expressing a decimal number as a ratio of two integers, where the denominator is a power of 10. This process can be useful in various mathematical operations, such as adding and subtracting fractions, and simplifying complex expressions.
Converting 1.8 to a Fraction
To convert the decimal number 1.8 to a fraction, we need to express it as a ratio of two integers. We can start by writing the decimal number as a fraction with a denominator of 10:
1.8 = 18/10
Now, we can simplify the fraction by dividing both the numerator and denominator by 2:
18/10 = 9/5
So, the decimal number 1.8 can be expressed as the fraction 9/5.
Understanding the Simplification Process
The simplification process involves finding the greatest common divisor (GCD) of the numerator and denominator and dividing both numbers by the GCD. In this case, the GCD of 18 and 10 is 2, so we divided both numbers by 2 to simplify the fraction.
Visualizing the Fraction
To visualize the fraction 9/5, we can use a circle or a rectangle divided into 5 equal parts, with 9 of the parts shaded.
This visual representation can help us understand the concept of fractions and how they relate to decimal numbers.
