Word Problem Wednesday: Birthday Math

Sep 6, 2017 | Diamond Bar


How old are you?

If you know when your birthday is then you know your basic age, but do you know your more exact age? When is your half-birthday? (It’s the day of the year that is exactly 6 months from your birthday.) When is your quarter birthday? Or your three-quarter birthday? When you use math, EVERY DAY becomes a day to celebrate YOU! 

Use your super math skills to figure out the birthday-themed word problem challenge below. 

Word Problem Challenge: Peter’s birthdate is January 3, 1996. Hannah’s birthdate is October 30, 2008. How old will each of them be on August 25, 2017?

When you've thought it through and are ready, look below to check your solution with ours!

Solution: Since Peter’s birthday will already have happened this year, he will be 2017 – 1996 = 21 years old. Hannah’s birthday hasn’t happened yet, so her last birthday was in 2016. So, Hannah will be 2016 – 2008 = 8 years old.
