((Fyi ik this answer is l8 but I'm just going to help others on here))
This is what the question actually says: Mark and John were sharing the $10 cost to rent some video games with another friend. Mark paid $3, John paid 2/5 of the total, and their friend paid the rest.
Who paid the most towards the rental?
The answer would be John
<em>John paid 2/5 </em>or $4 of the total amount since 10 divided by 5 is 2, so if he paid 2/5 of the amount, it would be $4 dollars,
If you add Johns amount to Mark's, it'll be $7 dollars, so the other friend also paid $3 dollars for a total of $10 dollars!
As you can see, John paid the most out of the rental the friends shared.
Hope this helps!! :D
