There are two ties in the bass part of the following excerpt for a Drop D guitar part. Both of them include some other different notes. According to the tie's definition, 16th note + 8th note = 3/16th note. 

In the case of the first tie, should I play a 3/16th note at the beginning of the second measure, or shall I play a whole 3/8th note?
