Frequently Asked Questions: Ratios with Decimals
Common questions about simplifying decimal ratios.
First, multiply both terms by a power of 10 to clear the decimal point. Once they are whole numbers, find their Greatest Common Factor (GCF) and divide both terms by it.
Take 1.5 : 2.5. Multiply both by 10 to get 15 : 25. The GCF of 15 and 25 is 5. Divide by 5 to get the simplified ratio: 3 : 5.
