What is 0.392 as a fraction?

In this article, we will guide you step by step through the process of converting the decimal 0.392 into a fraction. We will start by understanding how a decimal represents the fractional part of a number, then break down the steps to rewrite 0.392 as a fraction. Finally, we will simplify the fraction by identifying and applying the Greatest Common Factor, ensuring the results are in the simplest form.

By the end of this guide, you should have a good understanding of decimal to fraction conversions and be able to apply this knowledge to various mathematical problems. Let's begin.

0.392 as a fraction equals 392/1000 or 49/125

Now let's break down the steps for converting 0.392 into a fraction.

Step 1:

First, we express 0.392 as a fraction by placing it over 1:
0.392/1

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point.
0.392 x 1000/1 x 1000
  =  
392/1000

Step 3:

Next, we find the Greatest Common Factor (GCF) for 392 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.
The factors of 392 are: 1 2 4 7 8 14 28 49 56 98 196 392
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The GCF of 392 and 1000 is: 8

Step 4:

To simplify the fraction, we divide both the numerator and denominator by their greatest common factor (GCF), which we calculated in the previous step. The GCF value is 8 in this case.
392 ÷ 8/1000 ÷ 8
  =  
49/125


Great Work! We've just determined that 0.392 as a fraction equals 392/1000 or 49/125 in its simplest form.

Frequently asked math questions, including decimals and fractions

Read the following section to help deepen your understanding of basic math concepts.

What are whole numbers?

Whole numbers are numbers 0, 1, 2, 3, etc. Whole numbers do not have a decimal point or fractional part. Whole numbers are always positive. Negative numbers are not considered whole.

What are simple or reduced fractions?

Simple or reduced fractions are fractions whose top number (numerator) and bottom number (denominator) cannot be any smaller, while still being a whole number. That is to say, the number can no longer be divided by any number other than one while still being a whole number. 1/3 is a good example of a fully reduced fraction.

What is a ratio?

A ratio is a relationship between two numbers that shows how many times one value is contained within another. For example, the ratio 3:1 means there are 3 parts of one quantity for every 1 part of another.

What is a terminating decimal?

A terminating decimal is a decimal number that has a finite number of digits after the decimal point. For example, 0.35 and 3.5 are terminating decimals.

What is a repeating decimal?

A repeating decimal is a decimal in which a digit or group of digits repeats infinitely. For example, 0.3333... (where 3 repeats forever) and 0.142857142857... (where 142857 repeats) are repeating decimals.

What is a fraction bar?

A fraction bar is the horizontal line that separates the numerator and denominator in a fraction. It also represents division. For example, in 2/4, the fraction bar means 2 divided by 4.
