Commas should be placed after every third number in a sequence, if that number has more than three numbers. So, here are your answers:
A. 13,886
B. 365 (no comma because this number has only 3 digits)
C. 719,463
D. 40,047,209
E. 2,145,739,180
F. 1,783,457
P.S. You start placing commas from the final number and then move onto the first one.

To place commas in number, you need to count 3 numbers each starting from the back. The numbers need to be in three pairs. After each third number, add a comma. So that will be;

a.) 13886. If you count three numbers from the back, you will stop at 8. So that will be; 13,886. The rest follow the same pattern.

b.)365
It does not have a comma because the third number is the last number.

c.)719,463

d.)40,047,209

e.)2,145,739,180

f.)1,783,457
Hope that helped. Have a nice day
