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.

0.28475 as a fraction equals 28475/100000 or 1139/4000

Now let's break down the steps for converting 0.28475 into a fraction.

Step 1:

First, we express 0.28475 as a fraction by placing it over 1:
0.28475/1

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point.
0.28475 x 100000/1 x 100000
  =  
28475/100000

Step 3:

Next, we find the Greatest Common Factor (GCF) for 28475 and 100000. Keep in mind a factor is just a number that divides into another number without any remainder.
The factors of 28475 are: 1 5 17 25 67 85 335 425 1139 1675 5695 28475
The factors of 100000 are: 1 2 4 5 8 10 16 20 25 32 40 50 80 100 125 160 200 250 400 500 625 800 1000 1250 2000 2500 3125 4000 5000 6250 10000 12500 20000 25000 50000 100000
The GCF of 28475 and 100000 is: 25

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 25 in this case.
28475 ÷ 25/100000 ÷ 25
  =  
1139/4000


Great Work! We've just determined that 0.28475 as a fraction equals 28475/100000 or 1139/4000 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 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 are composite numbers?

Composite numbers are numbers that are greater than 1 and have more than two factors. For example, 6 is a composite number because it has factors 1, 2,3 and 6.

What is a square root?

The square root of a number is a value when multiplied by itself, gives that number. For example, the square root of 9 is 3 because 3 × 3 = 9.

What is a mean (average)?

The mean, or average, is calculated by adding all the numbers in a set and dividing by the total number of values. For example, the mean of 3, 4, and 5 is (3 + 4 + 5)/3 = 4.

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 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.
