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.

1.6125 as a fraction equals 16125/10000 or 129/80

Now let's break down the steps for converting 1.6125 into a fraction.

Step 1:

First, we express 1.6125 as a fraction by placing it over 1:
1.6125/1

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point.
1.6125 x 10000/1 x 10000
  =  
16125/10000

Step 3:

Next, we find the Greatest Common Factor (GCF) for 16125 and 10000. Keep in mind a factor is just a number that divides into another number without any remainder.
The factors of 16125 are: 1 3 5 15 25 43 75 125 129 215 375 645 1075 3225 5375 16125
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
The GCF of 16125 and 10000 is: 125

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 125 in this case.
16125 ÷ 125/10000 ÷ 125
  =  
129/80


Great Work! We've just determined that 1.6125 as a fraction equals 16125/10000 or 129/80 in its simplest form.
