What Is a Ratio?
A ratio compares two quantities by division. The ratio A:B means "for every A units of the first quantity, there are B units of the second." Ratios can be simplified by dividing both terms by their greatest common divisor (GCD).
Frequently Asked Questions
How do you simplify a ratio?
Divide both parts of the ratio by their greatest common divisor (GCD). For example, 12:8 simplifies to 3:2 because GCD(12,8) = 4.
Can ratios have decimals?
Yes. This calculator accepts decimal inputs and will simplify the ratio. For example, 1.5:2.5 simplifies to 3:5.
What does it mean when two ratios are equivalent?
Two ratios are equivalent if they simplify to the same ratio. For example, 2:3 and 4:6 are equivalent because both simplify to 2:3.
