For my first unit i wanted to share my knowledge on fractions with my step by step math tutorial.
Since i am late with this assignment i will be breaking down multiplying and dividing fractions with and i dont have my phone to take a photo of my math, so i have to do allll my math on here so bear with me it will look bad ðŸ˜. First i will say the steps then i will show an example and for a referance in this will be that the first number before the / is the top number/the numerator and the second number after the / is the bottom number/the denominator
First: Multiplying fractions, the step by step math tutorial.
example question :Â 14/8 x 4/7
1. you get your fraction
2. for an easier time you start with cross multiplication. Cross multiplication is where you go diagonally and dividing the number by however many it is divisible by. For example 14 is across from 7 in the fraction and if you divide 7 by 14 you get 1 and 2. Then you cross multiply 8 by 4, which you do the same steps. 4 divided by 8 which is equal to 1 and 2
Currant fraction: 2/2 x 1/1Â
3. You then multiply the numerators and the denominator which equal to 2 x 1 and 2 x 1
4. It then equals to 2/2 then you divide 2 by 2 which equal to 1
ANSWER: 1 WOOHOOOOOOO
Second: Dividing fractions, the part 2 of the step by step tutorial. (since i dont know what a division sign is on here im just going to use * as the division sign)
Example Question: 3/14 * 9/7
1. you get the fraction
2. you flip the second fraction. As an example the second number in this is 9/7, and when you flip the fraction you switch the bottom number with the top number, so that is ends up as 7/9 and once you flip the fraction the division sign (*) turns into a multiplication sign (x)
Currant fraction: 3/14 x 7/9Â
3. As you learned from the last step by step tutorial on multiplication you cross multiply the fraction and then you multiply it. Ill do the work for you as an example.
4. the same part as multiplication
1. 3/14 x 9/7
2. 1/2 x 3/1
3. 1 x 2 = 2 then 1 x 3 = 3
4. 2/3
The answerrr: 2/3 woo hooo
Thank you for letting you let me help you learn fractions. Sorry if this looks really confusing ðŸ˜
