The sum of two numbers is equal to the product of two numbers. What's the rule? I'm in a hurry

Let these two numbers be x and Y respectively, then the relation they satisfy is: x + y = x.y. from this condition, we can get: x = Y / (Y-1)
Suppose y = 1.5, then x = 3
If y = 2, then x = 2
If y = 3, then x = 1.5
If y = 5, then x = 1.25
Remember to adopt it

3 times 4 equals 12 (12 is certain). What's the ratio?

If AXB = 12, we can say that a and B are inversely proportional

If 6 times 8 equals 12 times 4, the ratio less than 1 is ()

When 6 times 8 equals 12 times 4, the ratio less than 1 is 6:12 = 4:8
