- Hiii class! So today we'll be discussing how to multiply, add, and subtract fractions. Lets get started!
- Theme song starts playing
- I'll be explaing how to multiply fractions together. When you multiply fractionsthe denominator doesn't have to be the same, you can just multiply the numerators together then the denominators
- 2/6 x 3/6= 6/12. You can leave the fractions like that if there isnt a number that go into both the numerator and the denominator, but since there is for this question you have to simplify the fractions by dividing them by the gcf
- 6/12 divided by 6+ 1/2. Another way you can multiply fractions is by simplifying it by dividing the denominator and numerator by their gcf.
- First step you need to do is find the lowest common multiple of the denominators. After you find the lowest common multiple for 9 and 3 which is 9
- To get to 9 you multiply by 1. To get to 9 from 3 you multiply by 3. Then you multiply the numerators. You then subtract the new numerators together but the denominators stay the same. Then you have your answer
- I will be teaching you guys how to multiply fractions with different denominator. So first you have to find the lowest common multiple of 6 and 12, ad that would be 12. T
- Then whatever you multiplied by to get your lowest common denominator, you multiply by the numerator for both sides, so 6 to get to 12 you multiplied by 2 so you multiply 3 by 2 which would be 6. and you multiplied 12 by 1 to get to 12 so you multiply 1 by 5 which is 5
- And thats how you add, subtract, and multiply fractions. We hope you enjoyed!
