Understanding the decimal: “1.8”
A decimal number has an integer and fractional parts. The decimal point separates the two. The integer is to the left, the fraction to the right. For example, in 1.8, 1 is the integer and 8 is the fraction.
- For the numerator:
- We start with the number 1.8.
- By removing the decimal point, we derive the numerator as 18.
- For the denominator:
- Each position after the decimal represents a division by 10.
- Thus, having 1 positions after the decimal equates to 10 or 101.
- The factors for the numerator and the denominator are numbers that can evenly divide each of them.
- For instance, the factors of 18 include 1, 2, 3, 6, 9, and 18.
- The factors of 10 comprise 1, 2, 5, and 10.
- Greatest Common Divisor (GCD):
- It's the largest number that can evenly divide both the numerator and the denominator.
- In this instance, the GCD for 18 and 10 is 2.
The factors of 18 are:
The factors of 10 are:
