Converting 4.64 decimal to fraction gives approximately 116/25.
To convert 4.64 to a fraction, multiply by 100 to clear the decimal, getting 464/100, then simplify by dividing numerator and denominator by their greatest common divisor, which is 4, resulting in 116/25. This method makes it easy to change decimal to a simplified fraction.
Understanding the Conversion
The process involves eliminating the decimal point by multiplying the number by a power of ten, based on the number of decimal places. Then, you simplify the resulting fraction by dividing numerator and denominator by their common factors. This ensures the fraction is in its simplest form, accurately representing the decimal.

Conversion Formula
The formula to convert decimal to fraction involves multiplying the decimal by 10^n, where n is number of decimal places, then dividing the result by the same power of ten. This converts decimal into an equivalent fraction. Simplify the fraction by dividing numerator and denominator by their gcd.
For example, 4.64 multiplies by 100 (since 2 decimal places), yielding 464/100. The gcd of 464 and 100 is 4, so dividing numerator and denominator by 4 gives 116/25, the simplified form.
Conversion Example
- Number: 3.75
- Step 1: Count decimal places, 2, so multiply by 100: 3.75 * 100 = 375
- Step 2: Write as 375/100
- Step 3: Find gcd of 375 and 100, which is 25
- Step 4: Divide numerator and denominator by 25: 375/25=15, 100/25=4
- Result: 15/4
