What is a Three-Part Ratio?
A three-part ratio (written as A : B : C) compares three distinct quantities simultaneously. Unlike standard two-part ratios, a three-part ratio maintains mutual proportionality across three terms, making it essential for recipes, chemical formulations, concrete mixes, and multi-partner equity sharing.
Simplifying a three-part ratio involves finding the Greatest Common Divisor (GCD) of all three numbers and dividing each term by that common factor. For example, the ratio 12 : 18 : 24 shares a common divisor of 6, simplifying cleanly down to 2 : 3 : 4.

Vanliga Frågor
How do you simplify a three-number ratio? ▼
Find the greatest common divisor (GCD) of all three numbers, then divide each of the three terms by that common number.
Can a ratio have three parts? ▼
Yes, ratios can compare three, four, or any number of quantities written with colons like A : B : C.
How do you divide an amount into three parts using a ratio? ▼
Add the three ratio numbers together to get total parts, divide your total amount by the sum of parts to find one unit part, then multiply each ratio number by that unit value.
What if one of the three numbers in a ratio is a fraction? ▼
Multiply all three terms by the least common multiple (LCM) of the denominators to clear all fractions into whole numbers.
How do you convert a 3-part ratio to percentages? ▼
Add the three terms to find the total parts, then divide each term by the total parts and multiply by 100%.
