Lesson 9: Converting US customary units word problems

# Measurement word problem: blood drive

The video dives into the concept of converting units within the US Customary system. It emphasizes the process of moving from smaller units (like pints) to larger ones (like gallons), and how this affects the quantity. It's all about understanding the relationships between different units of measurement. Created by Sal Khan and Monterey Institute for Technology and Education.

• So is multiplying by a fraction the same as dividing?
• Yes, multiplying by 1/2 is the same as dividing by 2. Or in more common language, you are "taking half of the amount".
• 1 gallon = 4 quarts
And 1 quart = 2 pints
So, there are 8 pints = in 1 gallon.
• Yeah. Another way to think about it is that there is 1/2 a quart in a pint. And 1/4 a gallon in a quart. Multiply 1/2 and 1/4 together to get 1/8. There's 1/8 a gallon in a pint.. You would take 80 pints and multiply by 1/8 gallon to get the same answer, 10 gallons.
• how do you add 7222.98 and 300.7456 multiplyed
• That is a hard question, you should take your time.
• hello do you 156 divided by 7 =
• I thought that little dot that Khan draws is supposed to be only for multiplication ( because that's how he used them in his past vids )......or is it just a sort of variable?

• Yes and I put 5 videos on at a time.
