Partitive Proportions are like these:

4:5 has the sum of 45 what are the ratios?

To have the answer, simply add the numbers 4 and 5 which is equal to 9 and divide it to 45 which is equal to 5 then multiply 4 and 5 to 5 which is equal to 20 and 25 therefore, 4:5=20:25, 20 and 25 has a sum of 45

There are proportions like that.. the ratio has a sum of --- ; the ratio has a difference of --- ; the ratio has a product of --- ...

That's one of the example of Partitive Proportion
