Do the ratios 2015 and 129 form a proportion?

To determine if the ratios 2015 and 129 form a proportion, we need to have another pair of numbers to compare them to. A proportion is a statement that two ratios are equal. So, for example, if we had the ratios 2015:100 and 129:6.4, we could say they form a proportion because 2015/100 = 129/6.4.

However, with the information given, we can't determine if 2015 and 129 form a proportion because we don't have another pair of numbers to compare them to.
