Often, convert 5.74 to a fraction or 5.76 to a fraction, depending on the task.

Understanding the decimal: “5.75”

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 5.75, 5 is the integer part and 75 is the fractional part.

Conversion Explanation:

  1. For the numerator:
    • We start with the number 5.75.
    • By removing the decimal point, we derive the numerator as 575.
  2. 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.
  3. Factors:
    • The factors for the numerator and the denominator are numbers that can evenly divide each of them.
    • For instance, the factors of 575 include 1, 5, 23, 25, 115, and 575.
    • The factors of 100 comprise 1, 2, 4, 5, 10, 20, 25, 50, and 100.
  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 575 and 100 is 25.

The factors of 575 are:

1 5 23 25 115 575

The factors of 100 are:

1 2 4 5 10 20 25 50 100

Conversion formula (equation):

5.75=5.751=5.75 × 1001 × 100=575100=575÷25100÷25=234

Solution:

5.75 = 234

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. 5.75 = 5.751
  • Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 5.75, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 102 = 100
  • Step 3: Using this factor, multiply both the numerator and the denominator. 5.75 × 1001 × 100 = 575100
  • 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. 575 ÷ 25100 ÷ 25 = 234

Answer in mixed fraction format:

5.75 =
5
