Ratios
express a relationship between two numbers. For example, the ratio 3:5,
in terms of shots made and shots taken, means that three out of every
five shots goes in. When you have multiple ratios, you may want to
determine whether they are equal or if one of them is larger. To compare
ratios, you need to have a common second number. By multiplying each
ratio by the second number of the other ratio, you can determine if they
are equivalent.

Multiply both numbers in the first ratio by the second number of the
second ratio. For example, if the ratios are 3:5 and 9:15, multiply 3 by
15 and 5 by 15 to get 45:75. </span><span>
Multiply both numbers in the second ratio by the original second
number of the first ratio. In this example, multiply 9 by 5 and 15 by 5
to get 45:75. </span><span>
Compare the results. If the results are equal, the two ratios are
equivalent. If not, they are not equivalent and the ratio with the
higher first number is larger. For example, if you had started with the
ratios 3:5 and 12:15, you would get 45:75 and 60:75. Since the second
ratio has the higher first number, (60 is greater than 45), 12:15 is
larger than 3:5. </span></span>
