0.7	Obviously important	Element i is significantly more important than element j
0.8	More important	Element i is much more important than element j
0.9	Extremely important	Element i is extremely more important than element j
0.1, 0.2, 0.3, 0.4	Inverse comparison	The result of comparing the importance of element i over element j is bij; then element j is more important by 1- bij than i.
