How It Works
A fraction is a division problem. 50/55 means 50 divided by 55. 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 50/55, that is 50 ÷ 55 = 0.(90).
Percent = (numerator × 100) ÷ denominator. For 50/55, that is (50 × 100) ÷ 55 = 5000 ÷ 55 = 90.(90)%.
Simplest form divides the numerator and denominator by their greatest common divisor. 50/55 in simplest form is 10/11. 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.
