7 Maths GCSE Questions

[kaiowas]

The problem I have is I cannot do simple calculations without using a calculator, those I can do take a long time such as percentages. I always have to work out 1% just by moving the decimal place along first then I can times that by 17.5 to get 17.5%.

I couldn't do the trig questions without a calculator though (unless I did an accurate drawing).

Working out 17.5% is a lot easier that it looks at first glance

Working out 10% is easy right? Anyone can divide by 10.
5% is easy to, all you need to do is halve the number above.
2.5% is just as easy, halve it again.

Add those three numbers together and you've got 10% + 5% +2.5% = 17.5%

Got 7/7.

I'm ready to be headhunted by MI6 as their top codebreaker.

What's so hard about trig? It's only ****ing cos.

6/7 - Fraction question tricked me I did A level maths too

 

[muon]

What is one third of 301?

 

[SlyReaper]

What is one third of 301?

100 + 1/3.

Note the "+" there. It makes things far less ambiguous.

 

[muon]

100 + 1/3.

Note the "+" there. It makes things far less ambiguous.

Ask 100 people and I doubt any would write 100 + 1/3. I would bet the mixed fraction form is the most common.

 

[semi-pro waster]

What is one third of 301?

100.33..., 100.33r or 100 & 1/3 or 301/3? I'd be more likely to use the second option as I think it's the least ambiguous but potentially any of them would do the job and the last option I might use because I was taught that you can leave such things as irreducible numbers if the question doesn't specify otherwise.

//edit bah, I got a phone call in the middle of typing this and so I now see your answer above.

Mixed numbers have been on the GCSE curriculum for at least a decade, presumably everyone that is seemingly completely baffled by them is over 30?

 

[muon]

100.33..., 100.33r or 100 & 1/3 or 301/3? I'd be more likely to use the second option as I think it's the least ambiguous but potentially any of them would do the job.

I personally would never use recurring notation when a fraction would very easily do the job.

I would use the mixed fraction. It is the most intuitive answer.

If I'm lazy and answering for Mathematicians then I'd leave it at 301/3.

 

[estebanrey]

What is one third of 301?

100.333...

Once you understand that 0.999... = 1, then 0.333 recurring really isn't that hard to understand. I don't accept the "it looks ugly" argument either but that's subjective.

I'm 33 so yeah

I was taught them and thought they were stupid I went on to do A level maths + further maths/

I've done A level maths and an engineering degree since GCSE too, doesn't mean i've completely forgotten everything from school and was totally dumbfounded when a quiz asked me about mixed numbers specifically

 

[Cleisthenes]

I would do it but I can't be bothered to go to my room to get a calculator

 

[marc2003]

I would do it but I can't be bothered to go to my room to get a calculator

what internet capable device are you posting from that doesn't have a calculator?

 

[hawker1986]

7/7, did it in my head, pretty happy been 10 years since ive done A Levels

Hawker

 

[Merlin5]

3, feeling thick as ****.

Haha, dumbass.


























I got 2.

LOL, 3 and 2!





















































Yeah I got 2

 

[Bald-Eagle22]

Ooh err 4 .

 

[Morba]

I have a maths degree and got 6 out of 7. I'm convinced this question:

...is complete bollards. On what planet does 4*(3/5) - 2*(1/3) make 34/15?

And then it occurred to me that the question actually meant "four and three fifths minus two and one third". So yeah. No mathematician ever writes numbers that way. In fact, I've never seen anyone write numbers that way. BBC: tripping up real mathematicians by being annoyingly ambiguous.

That's the one I got wrong as couldn't figure it out for any of the options. Afterwards I thought the same as you, it was just the way it was written!

 

[albert]

All these sums are complete tosh and rubbish .... If there's something about you, you have a good attitude, you can read and write then i'll give you a chance at Nissan UK. You'll be amazed at how many school leavers who attend interviews that can't read or write.

Off the record the schools are churning out a conveyor belt of zombies with no social skills, happy to play Xbox/PlayStation with all their 'friends' online. The strange thing is the lads that's failed their probation at NMUK because they can't read or write are fully proficient in sending texts or messaging on Facebook.
