What happens here

This video provides a step-by-step instructional guide on how to subtract mixed fractions. It covers the essential steps of converting fractions to a common denominator and the process of 'borrowing' from the whole number when the numerator of the first fraction is smaller than the second. While not a traditional physical 'DIY project', it teaches a foundational mathematical skill that is a 'do-it-yourself' mental exercise applicable in various practical scenarios.

All right, let's subtract fractions. So, let's say we got 11 and 9/16 5 and 5/8, right? All right, let's turn this one to the 16. So, * 2. What you do on here, you got to do on here, right? So, 10 over 16, right? Boom, boom, boom, boom, boom. Okay? So, let's rewrite this. 5 and 10/16. So, now you got to take 9 - You can't do that. You can't do 9 - 10 cuz you get -1. That don't work, right? So, what we did in previous videos, we added these two. So, we got to do 25 over 16. But, in order to do 25, you got to borrow from the 11, right? So, that turns that into a 10. Easy day. So, let's rewrite all of this and we got 10 and 25/16 5 and 10/6 16. Got it? Let's subtract our whole numbers. We got 5. Subtract our numerators. We got 15/16. That's it. Easy day. Let's run it back, something a little easier. Erase. All right, this one might be easier. Let's run it. So, you got 11 and 3/4 - 3 and 3/8, right? So, we know we got to change this one to an 8 cuz you got to have the same denominators before you even do anything. So, let's just run it. Multiply by 2 again. So, this is 6 8, right? So, we have 11 and 6/8 - 3 and 3/8. Worry about the whole numbers, right? 11 - 3 8. Easy day. 6 3 3. Keep your denominator, 8. Boom. Done. Easy. It's all you got to worry about right there. Follow for more.
