Answer:
A) The sum of given digits is 5417.412 
B ) The sum of given digits is 401.103  
Step-by-step explanation:
Given sum of numbers as :
A ) 5 × 10³ + 4 × 10² + 1 ×  + 7 ×
 + 7 ×  + 4 ×
 + 4 ×  + 1 ×
 + 1 ×  + 2 ×
 + 2 ×  
 
Or , 5000 + 400 + 10 + 7 × 1 + 0.4 + 0.01 + 0.002
or, ( 5400 + 10 + 7 ) + ( 0.4 + 0.01 + 0.002 )
Or, 5417 + 0.412
Or, 5417.412
Hence The sum of given digits is 5417.412 
B ) 4 × 10² + 1 × ( 1  ) + 3 ×
 ) + 3 ×  
 
Or, 400 + 1 × ( ) + 0.003
 ) + 0.003
Or, 400 +  + 0.003
 + 0.003
Or, 400 + 1.1 + 0.003
Or, 401.103 
Hence The sum of given digits is 401.103
