This video made me a new subscriber 😊✌🏽 I forgot to turn the problem into an improper fraction. I was stuck on a problem for about 10 min and this video instantly refreshed my mind. I’m currently studying for an electrician’s apprenticeship aptitude test. I’m pretty sure I’ll be using more of your videos very soon! Thank you for your service 👍🏽👍🏽
To get the mixed fraction is to divide 287÷12 use long division to make it easier and to make it is the quotient will be the whole number which is 23 the Numerator will be the remainder which is 11 and copy the Denominator which is 12 Pls correct me if I'm wrong
Can you do the same cross reduction for a whole number x a fraction? Preparing for ALEKs math placement and another video someone didn’t cross reduce 🧐 thank you!
Hi I need some help on dividing fractions by whole numbers I’m just confused on them do you mind making a video of how to do it ? Also, you do great videos you’ve helped me so much !
To divide a fraction by a whole number. I'll use the example of 3/5 divided by 6. Express 6 as a fraction, with an implied denominator of 1: 6 = 6/1 Your problem becomes: 3/5 divided by 6/1 Flip the second fraction, and make it a multiplication: 3/5 * 1/6 Cross-cancel the 3: 1/5 * 1/2 = Answer: 1/10
Just in case, all you have to do is add your fractions which would be 1 whole, and add your whole numbers with that whole number. That would give you 5, now all you have to do is subtract that by 2, which would be 3. Hope that helped!
Hi I’m in 7th grade and I signed up for IMO! The logical reasoning problems are quite hard 😭 Can you please solve some of them so I can get an idea of the concepts? Tysm!
If it isn't specified, you can leave your answer as an improper fraction, or you can convert back to a mixed number, whichever you prefer. If you did want a mixed number as the solution, you'd carry out the division problem. The remainder is your new numerator as a mixed number, and the division prior to the remainder is your new whole number.
You can multiply fractions without converting to improper fractions, but isn't as efficient. You'd express each fraction as an addition problem, and use FOIL (first outer inner last) to expand the expression. The reason you convert to improper fractions is that once you do the conversion, it is as simple as multiplying numerators to make the new numerator, and multiplying denominators to make the new denominator. Then you simply reduce it, and if desired, you translate it back to a mixed number.
Incorrect, the numerator is 287 and denominator is 12. 12 goes in 287 23 times because 12 x 23 = 276 and the remaining amount from the numerator is 11 so it becomes 23 and 11/12
So easy. I use cancellation because it’s fast just copy the 1st numerators and denominators then change division to multiplication then flip the divisor (the next numerator denominator) then use cancel method like this tutorial without the whole numbers then after you cancel you multiply then that is your final answer if it’s improper then make them mix number so how many you can get on the numerator and the denominator if you got it draw a line put the answer in the left side middle of the line, just search a tutorial.
Express each mixed number as an addition problem, and FOIL it out, to multiply the grouped addition problems. Using this example: (5 + 1/8)*(4 + 2/3) FOIL stands for first, outer, inner last. Multiply the first pair of numbers, then the outer pair, then the inner pair, then the last. Then add them together: 5*4 + 5*2/3 + 4*1/8 + 1/8*2/3 5*4 = 20 5*2/3 = 10/3 4*1/8 = 4/8 = 1/2 1/8*2/3 = 1*2 / (8*3) = 2/24 = 1/12 Convert all fractional terms to common denominators: 10/3 = 40/12 1/2 = 6/12 1/12, no need to change Add up numerators, and keep denominator of 12: (40 + 6+ 1)/12 = 47/12 Convert to mixed number and add it to the whole number term of 20. 47/12 = 3 + 11/12 20 + 47/12 = Answer as mixed number: 23+11/12
She turns mixed numbers into improper fractions. First, you need to multiply the denominator of the mixed number by the whole number. Then, add the numerator to that result. Finally, after multiplying the denominator by the whole number and added the numerator, then that result becomes your new numerator. Write your new numerator over the original denominator. Note: The denominator does not change So in the video for example, 5 1/8 and 4 2/3 would become 41/8 and 14/3 Because: 5 1/8 = ((8x5) + 1)/8 = 41/8 and 4 2/3 = ((3x4) + 2)/3 = 14/3 You see? Hope this helped
