Simplified a:b = (a ÷ GCD(a,b)) : (b ÷ GCD(a,b))GCD is the greatest common divisor. Divide both numbers by GCD to get lowest terms.
Decimal ratio = a / b
Multiply both by the same power of 10 to make integers, simplify, then divide back if needed.
Ratio compares two things (a to b), fraction is part of a whole (a/b).
