How It Works
A fraction is a division problem. 45/50 means 45 divided by 50. MathVibe divides those whole numbers exactly, writes the decimal, then multiplies by 100 for the percent. If the greatest common divisor is greater than 1, both parts of the fraction are divided by it to reach simplest form. Equivalent fractions are the simplest form multiplied by 2, 3, 4, and 5.
Formula & Logic Explanation
Decimal = numerator ÷ denominator. For 45/50, that is 45 ÷ 50 = 0.9.
Percent = (numerator × 100) ÷ denominator. For 45/50, that is (45 × 100) ÷ 50 = 4500 ÷ 50 = 90%.
Simplest form divides the numerator and denominator by their greatest common divisor. 45/50 in simplest form is 9/10. Repeating decimals keep the repeating digits in parentheses, so the displayed value stays exact. When that expansion does not terminate, a note also shows it rounded to 6 decimal places and the percent rounded to 2 places.

1/2 = 0.5 = 50%
- Read the fraction. 1/2 means 1 divided by 2. The numerator is 1 and the denominator is 2.
- Divide to find the decimal. Decimal = numerator ÷ denominator = 1 ÷ 2 = 0.5.
- Multiply by 100 to find the percent. Percent = (1 × 100) ÷ 2 = 100 ÷ 2 = 50%.
- Simplify the fraction. The greatest common divisor of 1 and 2 is 1, so 1/2 is already in simplest form.
- Build equivalent fractions. Multiply the simplest form by 2, 3, 4, and 5. 1/2 = 2/4 = 3/6 = 4/8 = 5/10.
3/4 = 0.75 = 75%
- Read the fraction. 3/4 means 3 divided by 4. The numerator is 3 and the denominator is 4.
- Divide to find the decimal. Decimal = numerator ÷ denominator = 3 ÷ 4 = 0.75.
- Multiply by 100 to find the percent. Percent = (3 × 100) ÷ 4 = 300 ÷ 4 = 75%.
- Simplify the fraction. The greatest common divisor of 3 and 4 is 1, so 3/4 is already in simplest form.
- Build equivalent fractions. Multiply the simplest form by 2, 3, 4, and 5. 3/4 = 6/8 = 9/12 = 12/16 = 15/20.
