so I’m going to teach you about add fractions with unlike denominators. I’m going to tell you a ways to answer the word problem and show you a video I made to help you under stand it more.
I ran 5/6 of a mile last weekend. This weekend I ran 7/18 of a mile. How much did I run in all?
one way to to this is by finding a common denominator to do that we need to find a number that is the same so for six you would have 6, 12,18,24… and for 18 it would be 18 and then we would stop because you see that 18 is in the six colum so you know that you don’t need to multiply the 7/18 but you do know that you need to multiply 5 and 6 by 3 because you always multiply denominator and numerator by the same number so you know that 5×3=15 and 6×3=18 so you know that your new equation is 15/18 +7/18 and the denominator always stays the same so you gust add the numerator and 15+7 =22 but that is more then 18 so you have to make it a mixed number so take 22 and dived it by 18 which = 1 and 4 remainder so you take the 4 and put it as the numerator and the 1 as the hole so the answer is 1 4/18 and that is how you Add Fractions with Unlike Denominators. https://www.youtube.com/watch?v=lGsFrln4lK0
Eva i love that you did this!! You did a great job explaining in such detail
Good job. You did it right. Just in the future be sure to capitalize.
That was really good. I noticed that you spelled a word wrong and it made the whole last part, not make sense. I did love how you explained everything so perfectly(other than at the end).
I think you did a great job explaining how to add fractions with unlike denominators. I love how you created a word problem! Here are a few things that I am still wondering…
1) You found the least common multiple in your video, however you did not use that term. Could you explain what that is?
2) Could you also explain why you always multiply your numerator when you multiply your denominator?
