This video is about Multiplying Fractions. Lyrics by Bill Murphy. All of the music is originally: Drop It Like It's Hot (Instrumental) (4:31) by Snoop Dogg feat. Pharrell Williams Drop It Like It's Hot - Single produced by The Neptunes. 2004 Geffen Records Lyrics: (Chorus) With the numbers in the numerator: Multiply across, multiply across, multiply across and the ones in the denominator: Multiply across, multiply across, multiply across When you're multiplyin' fractions just: Multiply across, multiply across, multiply across I got the temp turned down and my SmartBoard's gone and the only way to learn is listen to this song (Verse 1) I'm a nice dude, with some big dreams. But first I gotta do, all these fractions things. What if I had the fraction, 2 over 5, and then another one, and had to multiply? Like takin 2/5, and 1 over 3. If I multiplied 'em, just what would it be? Let me grab a pencil and a piece of paper. I'm gonna write this down so I don't forget it later: Multiply the numbers up in the numerator. Then do the same with the denominator. For our problem, start with 2 times 1. Now the top half's finished but we're still not done. Down on the bottom we got 5 times 3. Last time I checked that'll give us 15. 2/15 now I try to simplify. Looks like I can't so sing the chorus right. (Chorus) (Verse 2) That was easy, but ya'll knew that How about a challenge now? You know I had to do that. What if the numbers mixed? What do you do then? Just do the same thing as in verse 1 again? Can't do that or the numbers will get scrambled How 'bout a problem? Take this one for example: Like 4 2/3 times 2 ¼ Make 'em both improper fractions of course! 14/3 times 9 over 4 Before you multiply, you can simplify some more. Connect your numbers with one big x Then simplify those fractions using GCF's 7 over 1 times 3 over 2 multiply those numbers, and you're almost through 21/2 makes 10 ½ Now sing the chorus so you'll really learn this math. (Chorus) With the numbers in the numerator Multiply across, multiply across, multiply across and the ones in the denominator. Multiply across, multiply across, multiply across When you multiplyin' fractions just Multiply across, multiply across, multiply across I got the temp turned down and my SmartBoard's gone and the only way to learn is listen to this song (Verse 3) Now we're multiplyin, is there more to do? Let us take a sec and have a short review. If a number's mixed change it to improper. Then you simplify, c'mon boy do it proper. Multiply across, yeah that's what we sing. We can get these problems done before the bell rings. 3/8 times 4 over 5 Simplify 'em first before you multiply. 3 and the 5, those'll stay the same. 8 and the 4? Those'll surely change. Now 3 over 2 times 1 over 5. You get 3 over 10 after you multiply. You can times first and simplify it later but you may need to go and grab a calculator. When you learn with Murf, you can't go wrong. And if you forget, just sing this little song: (Chorus) With the numbers in the numerator Multiply across, multiply across, multiply across and the ones in the denominator. Multiply across, multiply across, multiply across When you multiplyin' fractions just Multiply across, multiply across, multiply across I got the temp turned down and my SmartBoard's gone and the only way to learn is listen to this song Show less
