Outstanding, it's been a few years and came across this on KZread so I decided to work it. Unfortunately I didn't come to the right answer but after watching your instructions I saw where I messed up and forgot one step. That's all it takes to make a mistake, miss just one step and your answer will be totally off. Thank You Very Much for posting this even though it was a year ago it definitely helped me bring out the stored information in my brain!

I finally got this one correct AFTER watching your Best Fraction HACK video!! THANKS SO MUCH FOR THESE VIDEOS for those of us who SUCK AT MATH!!

Agree about not giving a mixed number unless told to, either by the teacher or question in a test, but over here in an exam, such as GCSE, usually full marks are obtained at the unsimplified form and any further work is ignored. I say usually as this will be in the mark scheme and most I've seen do say ignore further working.

Thank you I wish you was my teachers back in the 60s

That is the long way of doing that. All u have to do is cross multiple. Common denominator is 15. Same answer. 40 - 48= -8 over 15.

I got the answer to this doing it in my head in about 20 seconds. Maths wasn’t my best subject at school, especially fractions but life’s needs such as calculating my finances has taught me.

Thanks for mentioning PEMDAS. In decades of math courses it was not mentioned. Ever. The teacher would write the problems from left to right, tell us that math is "logical," and be surprised that those of us familiar with logic would assume that problems are worked as written - from left to right. Ha! The great hidden secret was this PEMDAS thing which requires moving around according to the special symbols. You might get drummed out of the club for revealing classified information.

It doesn’t take 15 minutes to determine the least common denominator, multiply out, and subtract. 1 minute tops.

LCM=15. 22/3=8/3=40/15. 31/5=16/5=48/15 so 40+48=88. then 88/15=5 n 13/15. Ans

One could see the example problem like this: (2&2/3)-(3&1/5). If student can at least identify common denominator of 15, then expression is (2&10/15)-(3&3/5). The fraction part subtraction is done very easily, separately from the whole numbered parts. (2-3)+(10/15-3/15) -1+7/15 -(15/15)+(7/15) -8/15 Some students may need additional or slightly different steps.

not the funny thing is i was told to write the equation where the whole numbers go on the left and the fractions go on the right and then so on you people know who you are

Answer is _1/3

2.66666667 minus 3.2 equals negative 0.533333333333 or -53 over 100 or -53/100. The numerator and denominator are each divisable by 6.666666667. -53333333333/100 Reduced down equals -8/15. There! I saved you nearly 16 minutes.

This guy really dilly dollies around were you can lose focus

You are joking about converting the improper fractions to a mixed number. After all, that is inefficient in many cases. If you had 5 4/5 - 5 1/3 would you really convert to improper fractions? The sad thing is that you probably would. Because of teachers like you is the number one reason why students coming into college having to take my arithmetic course. This means that they learned absolutely nothing from grade 4 through grade 12-at least in math

@cbesthelper404

If students are underperforming because a Math teacher converted some mixed numbers into improper fractions, then those students would be struggling anyway. Perhaps the reason that he took that path with converting is that most students freak out when borrowing. So to avoid borrowing, teachers will expose students to this strategy. Other students don't mind borrowing. The point is, let the teacher teach. He knows what he is doing and why he is doing it. He knows his experience with students and what may digest more easily with them. Finally, a student could have the worst Math teachers in the world and still that would not necessarily provide a reason that they "learned absolutely nothing". Why? Because much of Math can be learned on your own, especially if you have access to a textbook, and nowadays several additional handy resources. So it is no excuse for college students to be entering college courses being Math illiterate. Good or bad teachers, sure it can make a difference. But any student who has progressed from 4th grade to 12th grade should have many basic Math skills under their belt, and probably had some very good Math teachers mixed in with some bad ones.

ARE YOU CERTAIN YOU REALLY PHRASED THE PROBLEM CORRECTLY? 2-2/3 = 8/3 and 3-1/5 = 16/5. The problem (X5) becomes: 40/15 - 48/15 = - 8/15. What an answer! minus (-) 8/15 ! Try: 3-1/5 - 2-2/3 and get a positive answer: 8/15. I am 68 and math was never my forte.

Sometimes you will get a negative answer. He did in this case. I would not doubt the phrasing of the problem based on that.

I did this a slightly different way. First of all I realised the answer had to be a negative. Then using the logic that the lower number fraction was larger than the higher number the answer could only be a fraction. After that it was simply finding the LCD then work out the answer to 2/3 minus 1/5 the answer would then be the negative of that calculation.
