If I was born on January 28,2004 what date will I become 15 and 1/2

July 28, 2019.

Step-by-step explanation:

15 1/2 years = 15 years and 6 months (A year is 12 months, so 1/2 a year is 6 months)

The year is the easy part. Since the amount of years in the age is 15, just add 15 to 2004:

2004 + 15 = 2019

For the month and day, let's imagine the months as numbers (January = 1, February = 2, etc.)

January is 1, so then 6 months added to it would be

1 + 6 = 7

7 is the number for July. So then the month is July. The day stays the same since the age provided does not have any count of days.

So you will be 15 1/2 on July 28, 2019.
