Question 1

How do I simplify a ratio with decimals, such as 1.5 : 2.5?

Accepted Answer

Multiply both terms by a power of 10 to clear the decimals (15 : 25), then divide by the GCD (5) to get 3 : 5.

Question 2

Can a ratio have more than two terms?

Accepted Answer

Yes. A : B : C works the same way: divide all terms by their common GCD, for example 4 : 6 : 10 becomes 2 : 3 : 5.

Question 3

How do I split an amount in a given ratio?

Accepted Answer

Add the terms to get the number of parts, divide the amount by that number, then multiply by each term. 100 split 2 : 3 is 40 and 60.
