Question

Insert commas in the following numbers. a. 13886 b. 365 c. 719463 d. 40047209 e. 2145739180 f. 1783457

Answer 1

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

Answer 2

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.
