I passed A level maths (grade 2) 60 years ago and enjoy maths problems, but this confused me. . To me, logically negative 4 times 2 over 3 is negative 8 over 3.

@laurendoe168 6 месяцев назад

It's not multiplication, it's addition. "Negative four and two thirds"

@scottmartin9041 6 месяцев назад

its just the way its written that confusing you. it (-4 2/3)is a number not -4 X 2/3 or -4 . 2/3

@tomtke7351 6 месяцев назад

when I see fractions I think about pies.... the 2/3 means a pie cut into thirds with 1 gone. The 4 is four full pies If they are also cut into thirds there would be 4 × 3 = 12 sections. So there's 2 3rds and 12 3rd for a total of 14 3rds = 14/3..

@ablair245 6 месяцев назад

After 40 years it was just like riding a bike - *Multiply the whole number to the denominator then add the numerator, keeping the denominator the same, 3. Because of the one negative, the negative will remain.

@dixiefire 6 месяцев назад

thanks for your math problems & help . . . I really like testing myself with them & reviewing ! This one is written strangely out of proportion with the 4 looking so small & the 2/3 looking so tall & big and the - sign looks oddly too large as well, same size as the line between the 2 & 3 fraction. . . but still only one way around it to solve . . . just looks weird & could throw some people off I suppose- but not if you have fractions down. -

@scottmartin9041 6 месяцев назад

I just think of the number line - 4 2/3 is the same as -4 - 2/3 which is -12/3 - 2/3 which is -14 /3

@MrMousley 6 месяцев назад

- 4 2/3 Well ... 4 is 12/3 ... plus the 2/3 ... and the remember it's minus - 14/3

@advancedautomotivemachine4791 6 месяцев назад

Took about 5 seconds ?? I guess what really bothers me is that "many will get it wrong" ? This is such basic math that I cannot imagine not knowing it after maybe 5th grade ?

@aryusure1943 6 месяцев назад

I went too fast and multiplied 12 by 2 instead of adding. So, I check all your boxes: Going too fast and being too confident because I saw - 24/3 in the choices. :( I offer myself as an example proving your demonstration. ;) We can know something and still make a mistake because we don't take the time. I knew how to solve this but my mind played a trick on me. BTW, I totally understand the way mutltiple choices are designed. Clever and effective!

That's horrible notation! I would read that as negative 4 multiplied by 2/3 (i.e. -8/3).

@dazartingstall6680 6 месяцев назад

If multiplication were intended it would be written −4(⅔) or −4 × ⅔. Mixed fractions like 4⅔ are always treated as a single unit, ie, in this case, as 4.66666...

@christopheroliver148 6 месяцев назад

@@dazartingstall6680 No! What I'm suggesting is that mixed fraction notation is a horrid thing. I would never parenthesize that way. Outside of perhaps a kitchen recipe, I'd far rather see an improper fraction which is a clear notation for a rational number than the awful mixed fraction notation which should simply go away. We're not setting kids up for future mathematical success by continuing with that botch.

@dazartingstall6680 6 месяцев назад

@@christopheroliver148 I get what you mean but I think you're seeing problems where none exist. In 57 years on this Earth I've never yet met anyone who misinterpreted a mixed fraction. 1½ is readily understood by all as one and a half. And while ³⁄₂ would certainly be just as readily parsed, I doubt we could say the same for, for example, ³⁰⁶⁄₇ as opposed to the more obvious 43⁵⁄₇. It seems to me you're reducing, not introducing, clarity.
