$$5*6=30$$

hero · Answer

If it forms a proportion, then after cross multiplication, both sides would be equal. For example, if you had

$$\frac{3}{8} = \frac{9}{24}$$

After cross multiplication you get
(3)(24) = (9)(8)
72 = 72

hero · Answer

Let try 5/8 and 6/12 to see if it forms a proportion:

$$\frac{5}{8} = \frac{6}{12}$$

After cross multiplication:
(5)(12) = (8)(6)
60 = 48? 
False

hero · Answer

Also we know it is not a proportion because 
6/12 = 50%
5/8 > 50%

The percentages of both fractions must be equal in order for a proportion to exist.
