to convert percentage into decimal you should divide by 100
a) 20.05%
20.05 ÷ 100 = 0.2005
b)3.75%
3.75 ÷ 100 = 0.0375

a)
20.05 %  = 20.05/100
to remove the decimals in numerator we have multiply by 100 in both numerator as well as denominator
i.e , 20.05 × 100 ÷ 100 × 100
  = 2005 ÷10000 = 0.2005

b)similarly ,
3.75 ×100 ÷ 100 × 100 = 375 ÷ 1000 =0.0375

There are many methods to convert percentages into decimals.
This is my method of doing.
