Frequently Asked Questions

Answers to common questions about this calculator

Divide both numbers by their greatest common divisor. Example: 12:18 = 2:3 (both divided by 6).
If a:b = c:x, then x = (b×c)/a. Example: 2:3 = 4:x → x = (3×4)/2 = 6
Divide the total by the sum of ratio parts, then multiply by each part. Example: distribute 100 in ratio 2:3 → 40 and 60.
