Lesson 1: Topic A: Proportional relationships

# Proportional relationships: bananas

A proportionality problem about eating bananas.

## Want to join the conversation?

• I have four questions:
.When a problem is not proportional, do we just say it's not proportional and go on to the next question?
.What kind of relationship is it if it's not proportional?

.Could we still solve it even if it's not proportional?
. And why would he waste money on 100 bananas? :)
• 1. Since there's a way to solve nonproportional relationships, you would still solve it (in a graph or a table).
2. Non-proportional :)
3. Yes, assuming the problem still makes sense.
4. Maybe he really likes bananas and they were on sale if you got 100 of them? idk
• Why don't nate's bananas go bad?
• he or she must've putted something or injected something to keep the bananas healthy
• to many bananas

• I understand proportions in other videos (it seems clear and simple to me), but this video confuses me. Any help?
• In this case he is presenting the type of problem that will generally look like it could be proportional because Nate is always eating two bananas a day, but with the way the question is worded (trick question almost) this particular problem is not proportional (proportional being as one number increases so does the other number at a constant ratio). It is more along the lines of inversely proportion which is as one number increases the other decreases.
• so... he's food poisoning himself by eating 49-day-old bananas?
• how he get so many bananas
• Had it been "Number of days left", it would have been a proportional relationship.
• i dont understand
cant you just divide without ratios?
• well sure but if you use ratios then youre doing it right and if you dont you will be executed so its kinda a lose lose

• I think that the question in this problem ("Is the number of bananas Nate has left proportional to the number of days that pass?") is not correct and it should be "Is the number of bananas Nate has left proportional to the number of days that HAVE PASSED?"

What do you think?
