Arithmetic
A ratio to percentage calculator converts a ratio a:b into a percentage by dividing a by b and multiplying by 100. It also provides the decimal, simplified ratio, and fraction with step-by-step work.
Divide the first number by the second and multiply by 100. For example, 3:4 = (3 ÷ 4) × 100 = 75%.
Percentages above 100% are valid when the first term exceeds the second. For instance, 5:4 = 125%.
percentage = (a ÷ b) × 100
