Two ratios comprise four numbers - one numerator and one denominator for each ratio. Most people do not find it easy to make comparisons involving four elements.

Now, if you use a common denominator, then the ratio with the smaller numerator is the smaller number. Only two numbers - the two numerators - to be compared.

Incidentally, you could use common numerators instead, but then the ratio with the smaller denominator would be the bigger number. Some of us do use this, particularly when the numerator is 1. eg 13>11 so 1/13 < 1/11.

How do you compare ratios-?

To compare ratios, compare the products of the outer terms by the inner terms.


How do you compare two ratios in two ways?

Treat the ratios as fractions. One way you can compare them is to convert them to decimal (divide the numerator by the denominator, or the first number of the ratio by the second number), then compare. Another way is to find a common denominator, then compare the numerators.


Which ratio is larger?

Put the two ratios across from each other with an equal between them. Multiply the lower number (denominator) by the top number (numerator) across the equals. The greater one tells you which is larger. What you have done is found common denominators equal to the product of the denominators.
