Lesson 3: Identifying proportional relationships

# Intro to proportional relationships

To know if a relationship is proportional, you should look at the ratios between the two variables. If the ratio is always the same, the relationship is proportional. If the ratio changes, the relationship is not proportional.

• What if an odd and even number were in a proportional.
• If an odd and an even were in a proportional like 2:3 it would just be like 4:6
• What is 23%of 80
• (1.) Turn 23% into the decimal .23.
(2.) Multiply .23 and 80.
(3.) .23 X 80 = 18.4
• Can you make this more easier like more understandable?
• Proportions are the same ratios written in different forms. A proportional relationship is states that they are the same. For example, 1/2 and 6/12 have a proportional relationship, which means they are the same.

I hope this helps!!

• Can I add a fraction
• yes ex: 1/4 + 3/4 = 1
• What is a rate?
(1 vote)
• A rate is essentially a constant. This constant cannot and must not change. Like Jada posed the example, I will take it one step further: A car is going at 25 miles per five hours, find the unit rate; the unit rate is actually just someone compared to one. So for every one of that object, there are x number of the other
• This is great.
I've been doing this for about an hour and it's growing on me. I'd like to give a big thanks to the guy who makes these.
• I totally agree
• Oh Please! I'm frustrated by this! I can't understand it!! Please I'm literally crying out of frustration! I've got a test soon, please break this down into easy parts. It would be nice.
• 6/2=3. 9/3=3. 3 is the constant of proportionality
