What do dogs do when life gets ruff? They go to the dog park, of course! And what do math students do when life gets rough? They call on Mathnasium, their A plus math tutors, for some fun word problem practice!

Unleash your elementary school math skills such as patterns, fractions and common multiples to solve this week’s word problem challenge. We know you’re gonna do grrreat!

Take your time thinking about the answer, and when you're ready, look below to check your solution with ours.

Question: Dana visits the dog park every 3 days. Carlos visits the dog park every 4 days. If both Dana and Carlos visit the dog park on Monday, what will the next day of the week be when both Dana and Carlos visit the dog park?

Solution: One way to solve this problem is to find the least common multiple of 3- and 4-day periods. Since the smallest number that both 3 and 4 go into is 12, the next day that both Dana and Carlos will visit the dog park will be 12 days after Monday, and 12 days after Monday is Saturday.

Before I came to Mathnasium, I could sum up everything I felt about math in one word: 'EVIL!' I hated math. ... Mathnasium has been my safe haven. They truly have shown me the light when it came to addressing my fear and provided me with the tools that I need to rebuild my prior knowledge so that I won't forget it. Math is no longer a subject I shy away from but it is a subject I can boldly accept and understand.
