Understanding the decimal: “0.3125”

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 0.3125, 0 is the integer and 3125 is the fraction.

Conversion Explanation:

  1. For the numerator:
    • We start with the number 0.3125.
    • By removing the decimal point, we derive the numerator as 3125.
  2. For the denominator:
    • Each position after the decimal represents a division by 10.
    • Thus, having 4 positions after the decimal equates to 10000 or 104.
  3. Factors:
    • The factors for the numerator and the denominator are numbers that can evenly divide each of them.
    • For instance, the factors of 3125 include 1, 5, 25, 125, 625, and 3125.
    • The factors of 10000 comprise 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 125, 200, 250, 400, 500, 625, 1000, 1250, 2000, 2500, 5000, and 10000.
  4. 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 3125 and 10000 is 625.

The factors of 3125 are:

1 5 25 125 625 3125

The factors of 10000 are:

1 2 4 5 8 10 16 20 25 40 50 80 100 125 200 250 400 500 625 1000 1250 2000 2500 5000 10000

Conversion formula (equation):

0.3125=0.31251=0.3125 × 100001 × 10000=312510000=3125÷62510000÷625=516

Solution:

0.3125 = 516

What is a decimal?

A decimal is a numeral system with a point. This point divides the integer from its fractional part. It provides a straightforward way to express and work with values less than one.
