![]() Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF. Next, given that you have x decimal places, multiply numerator and denominator by 10 x. First, count how many places are to the right of the decimal. Step 2: Remove the decimal places by multiplication.Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).Apply the negative sign to the fraction answer.Perform the conversion on the positive value.Remove the negative sign from the decimal number.How to Convert a Negative Decimal to a Fraction where the 857142 repeats forever, enter 0.857142 and since the 857142 are the 6 trailing decimal places that repeat, enter 6 for decimal places to repeat. where the 3 repeats forever, enter 1.83 and since the 3 is the only one trailing decimal place that repeats, enter 1 for decimal places to repeat. For a repeating decimal such as 1.8333.where the 36 repeats forever, enter 0.36 and since the 36 are the only two trailing decimal places that repeat, enter 2 for decimal places to repeat. For a repeating decimal such as 0.363636.where the 6 repeats forever, enter 0.6 and since the 6 is the only one trailing decimal place that repeats, enter 1 for decimal places to repeat. For a repeating decimal such as 0.66666.For repeating decimals enter how many decimal places in your decimal number repeat. Take the fraction and divide the numerator by the denominator.īecause you are converting a fraction of an inch, you have to divide the decimal amount of 0.8125 by 10 (fractions of an inch are in base 10) Īdd this to the previous amount of 18.583ġ8.5833 + 0.08125 = 18.665 rounded to three digits.This calculator converts a decimal number to a fraction or a decimal number to a mixed number. You know that the 18, the foot value, belongs before the dot. Now let's check this 18' 7 13/16" result for accuracy by converting it to a decimal. It is not always the case, but you are often better off using a higher amount for a denominator. Using a smaller denominator here produced a less accurate result. Now your result would look like 18' 7 2/2" - 18 feet- 8 inches If you had decided to make the denominator a 2, find the numerator of the fraction by multiplying 0.788 by a 2Ġ.788 * 2 = 1.576 rounded to the nearest whole number, 2 In this case, you have to round it upward, and the amount becomes 13.ġ3 is the numerator value of your fraction.Ĭollect all the results and place them together ġ8.649 in decimal feet becomes 18' 7 13/16" Multiply this amount by 16 and round the result to the nearest whole number to get the numerator of the fraction Take a step back to the remaining decimal 0.788. You have to pick a denominator that you can use, and in most cases, 16 as the denominator for the fraction is a good choice. Not much use, and hard to find a fraction with a denominator of 250 on your tape measure. The remaining decimal 0.788 is a fraction of an inch.Īs a fraction, you write it as 788/1000 simplified to 197/250 Remove this amount from the decimal, 7.788 ![]() The seven before the dot is the full inch value. The 18 is the foot value, and subtract this from the decimal amountĮxtract the whole inches of 0.649 by multiplying by 12 This amount is the numerator of your fraction. Multiply the leftover decimal by 16 and round this number to the nearest whole number. To be usable, 16 is a good choice for a denominator and still maintains an acceptable level of accuracy. 16, 8, 4 2 make good denominators, and if need be more precise, 64 can be the denominator. ![]() The denominator of 3365 has to change to a usable one that you can easily find on your tape measure. ![]() If you convert this to a fraction, you can end up with something that isn't very useful, like 2364/3365. The decimal amount that is left is a fraction value of one inch. This time the amount before the dot becomes the inch value. To get the number of inches, multiply the remaining decimal amount by 12. To convert a number in decimal feet format to foot inch and fraction first, remove the foot value.
