| 00:0-1 | Welcome to anywhere . Math Junior . I'm john I'm | |
| 00:02 | aided and today we're gonna be learning about multiplying fractions | |
| 00:24 | . Now let's get on to our first event . | |
| 00:26 | The set is going to paint a picture for Leo | |
| 00:28 | Leo Nardo da Vinci because he wants to earn money | |
| 00:31 | to buy pasta one day he saw painting that he | |
| 00:35 | really liked and he wanted it is the same candidate | |
| 00:38 | size . What is the area of the canvas as | |
| 00:41 | you can see in the picture says that his painting | |
| 00:45 | , The painting is 11 and 1/3 to win and | |
| 00:49 | the length is 16 and one half . So first | |
| 00:54 | you need to treat mixed numbers , these numbers into | |
| 00:57 | their proper fractions . So you need to change 11 | |
| 01:01 | , 1 3rd to 34 3rd and 60 and one | |
| 01:05 | half to 33 . Uh , and next , you | |
| 01:12 | know , You can simplify the numbers to simplify , | |
| 01:16 | you can see if one of the numbers is a | |
| 01:19 | factor of the numbers that died . So three is | |
| 01:23 | a factor of 33 . So you can cross that | |
| 01:25 | in 33 . And because 33 553 is 11 . | |
| 01:32 | This turns into 11 and listen to one And so | |
| 01:36 | to 34 1 x two as 17 . And so | |
| 01:42 | this U turn into one . But now we got | |
| 01:45 | everything simplified . We can start multiplying so 17 times | |
| 01:51 | . So what times we said it ? One seven | |
| 01:57 | , 187 . A final area of the campus is | |
| 02:02 | 187 inches . Weird . Here it is going to | |
| 02:09 | talk about party into this question . Okay now let's | |
| 02:12 | go on to our part B Leonardo lost the painting | |
| 02:16 | so much that he decides to frame it . The | |
| 02:19 | frame for his painting is 2.5 inches thick . He | |
| 02:23 | wants to hang the painting on a wall but there | |
| 02:26 | is only 340 inches squared of free space world of | |
| 02:30 | painting fit . So first you add two and one | |
| 02:36 | half two 11 1 3rd . And you also add | |
| 02:44 | to and have to 16 . Remember you don't have | |
| 02:50 | 200 half to 11 1 because there's four signs of | |
| 02:54 | a break . So you need to multiply 12 and | |
| 02:57 | one half 52 which would equal but then it would | |
| 03:00 | be 5 11 1 35.6 years . As john said | |
| 03:04 | you add five two 11 1 3rd and at five | |
| 03:12 | on to 16 if you simplify you get 16 And | |
| 03:20 | 1 3rd times 21 . And now You need to | |
| 03:28 | change this into an improper fraction 49 over three times | |
| 03:36 | for you , three Over two . So you can't | |
| 03:41 | simplify anymore . Now you finally multiple 2107 Over six | |
| 03:49 | . And that equals 51 one 1/6 . He just | |
| 03:59 | and as we said before the wall had 340 inches | |
| 04:03 | square . What the painting is ? 351 and 16 | |
| 04:08 | inches square . So over all , the painting will | |
| 04:12 | not fit on the wall . Now , here's some | |
| 04:14 | to try and europe . Thanks for watching . And | |
| 04:23 | if you enjoyed this video , please . |
