• I appreciate what he is doing and taking time out of his life to do this but he makes it more complicated than it has to be it could have just been.

36 inches in 1 yard = 36+36+36+36+18=162 <------theres your answer.

Why does he do it the long way??
• He wants to give people who are having trouble understanding what he is doing an explanation, so they can understand the concept better.
• How many yards are in a mile, this video is listed as the help for miles to yards question?
• 1,760 miles Jesse
• how many yards is in a mile
• A mile is 5,280 feet, and a yard is 3 feet.
So the number of yards in a mile is 5,280/3 = 1,760.
• how many miligrams are there in 5.6 kilograms
• You multiply 5.6 * 1000 to convert it to grams, and then multiply that answer by another 1000 to convert it to milligrams.
• At did he mean 12 inches per foot

• Sal said "12 inches per yard" but meant "12 inches per foot."
• I don't get this because when Sal is doing like feet or maybe yards n inches, how is he getting is answer by multiplying those words (yards, feet, inches). This is pretty a little confusing.
• hello math people or whatever yall call your selves these days sorry to bother u but I don't really get this video like the function of it I don't get what it is telling or saying I dont understand it can somebody help me understand this thank I want to learn this and do good on y exercise
• Your question brings up a good point.

I've completed Kindergarten to mid-Grade 4 right up to this video and I don't recall Khan covering CANCELLING OF UNITS as he has done here. But I should tell you that if you can get the hang of this you will take it right the way through to physics and any other type of complex calculations you care to learn.

I suspect that if you can't understand these ideas then your confusions lay not in this video but further back in your basic understanding of fractions. I would go back as far as you need to and then work forward again to fully grasp the ideas in this video.
• at Sal said there are 12 inches per yard. Aren't there 36?
• I think he meant 12 inches per foot and just got the terms "yards" and "feet" switched up.
• I don't really understand why he's multiplying the measurements in fraction form?
