Understanding the decimal: “0.975”

A decimal number consists of an integer part and a fractional part, separated by a decimal point. The integer part is on the left, and the fractional part is on the right. For example, in 0.975, 0 is the integer part and 975 is the fractional part.

Conversion Explanation:

  1. For the numerator:
    • We start with the number 0.975.
    • By removing the decimal point, we derive the numerator as 975.
  2. For the denominator:
    • Each position after the decimal represents a division by 10.
    • Thus, having 3 positions after the decimal equates to 1000 or 103.
  3. Factors:
    • The factors for the numerator and the denominator are numbers that can evenly divide each of them.
    • For instance, the factors of 975 include 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, and 975.
    • The factors of 1000 comprise 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, and 1000.
  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 975 and 1000 is 25.

The factors of 975 are:

1 3 5 13 15 25 39 65 75 195 325 975

The factors of 1000 are:

1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000

Conversion formula (equation):

0.975=0.9751=0.975 × 10001 × 1000=9751000=975÷251000÷25=3940

Solution:

0.975 = 3940

What is a decimal?

A decimal is a numeral system that includes a point to separate the whole number part from the fractional part. This system makes it easy to work with numbers less than one.

What is a fraction?

A fraction is a mathematical way of showing a part of a whole. It has two parts: the numerator on top and the denominator below, which help express partial values and comparisons.

Step-by-step solution:

  • Step 1: First, write the decimal as a fraction over 1. This sets up the next steps. 0.975 = 0.9751
  • Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 0.975, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 103 = 1000
  • Step 3: Using this factor, multiply both the numerator and the denominator. 0.975 × 10001 × 1000 = 9751000
  • Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 25. Divide both the numerator and the denominator by this common divisor. 975 ÷ 251000 ÷ 25 = 3940

Answer in mixed fraction format:

0.975 =
39
