Q&A for How to Convert a Decimal to a Fraction

0.043 = 43/1000. That's your answer, but (if you want) you can further reduce that fraction to approximately 1/25.

Use the same method described in the article above. Small decimal numbers just result in larger denominators in the equivalent fractions.

Move the decimal point two places to the right. That's the numerator. The denominator is 100.

Using the instructions in Method 1 above, 12.8 = 128 / 10, which reduces to 64 / 5.

Write an equation in which the fraction you're considering is set equal to x/1000. Then solve for x by cross-multiplying. For example: convert ¼ to thousandths. Set up this equation: ¼ = x/1000. Solve for x by cross-multiplying: (1)(1000) = (4)(x). So 1,000 = 4x, and x = 250. Thus, ¼ = 250/1000.

Convert to a mixed number by placing the numbers to the right of the decimal over 10. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator. 93/10.

It's already in decimal form. If you meant as a fraction, it'd be a mixed number: 4 1/10.

3.5 = 3 5/10 = 35/10.

Count the number of digits to the right of the decimal point. That's how many zeroes there will be following the 1 in the denominator of the fraction. 0.38 is equal to 38/100. Another example: 0.3801 = 3801/10,000.

-1.5 = -1 5/10 = -1 1/2 = -3/2.

Express it as 4,444 and 444/1000, which reduces to 4,444 and 111/250.
