Unable to Identify Error in Formula

Hi.. All

I need a help in a formula. I have a series of accuracy data ranging between 0 to 100 based on the accuracy line rates have to be calculated based on the below slabs.

Range - Rate (pesos)
Lines @ >=98% - 5
Lines @ >=95-97.99% - 4
Lines @ >=90-94.99% - 3
Lines @ >=85-89.99% - 2
Lines @ <85% - 0

I tried the below 2 formulas but what i noted is that when the accuracy is 85, 90 and 95 wrongs pesos are displayed

=IF(F2>97.99,"5",IF(f2>94.99,"4",IF(f2>89.99,"3",IF(f2>84.99,"2","0"))))
=IF(F147>98.00,"5",IF(F147>95.00,"4",IF(F147>90.00,"3",IF(F147>84.99,"2","0"))))
