Using cross-multiplying and a proportion to solve for an equivalent rate in a word problem. If you like this video, please leave a "thumbs up" or a comment! Check out my other math videos for more help :-)
Hi everyone! Thank you for your kind words and thoughtful responses. I'm adding more math videos to my channel, feel free to check them out for more math help!
look no one can teach this like you I am looking for people to teach me this cause I was trying to join the army and I'm happy now cause I found you do you do one on one teaching
If that's the case, what is the problem asking you to figure out? When you "solve" a proportion you are looking for the value that will make it a true, meaning it will be proportional. If you have 4 numbers, you can't "solve" the proportion. The problem might want you to just check to see if they are proportional.
I don't think this is unit rate because isn't unit rate a proportion where you have to find try to find the variable for one unit like 3/36=1/x. What you did was proportions with variables it was still a good video though.
In Chicago, the tax on a property assessed at $320,000 is $4,160. If tax rates are proportional in this city, how much would the tax be on a property assessed at $520,000? how do you work this problem
