Understanding the decimal: “2.75”
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 2.75, 2 is the integer and 75 is the fraction.
- For the numerator:
- We start with the number 2.75.
- By removing the decimal point, we derive the numerator as 275.
- For the denominator:
- Each position after the decimal represents a division by 10.
- Thus, having 2 positions after the decimal equates to 100 or 102.
- The factors for the numerator and the denominator are numbers that can evenly divide each of them.
- For instance, the factors of 275 include 1, 5, 11, 25, 55, and 275.
- The factors of 100 comprise 1, 2, 4, 5, 10, 20, 25, 50, and 100.
- 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 275 and 100 is 25.
The factors of 275 are:
The factors of 100 are:
