im so confused how would the ratio be 3/4 and 1/4 surley itd be 3/7 and 4/7

[paper plinth]

plz help i hate vectors

nvm i am stupid

i misread it as ac instead of oc

[young badger]

Wait, is it not 2/11 and 9/11 for ON: OB?

[sweet vortex]

yep lol

hopefully they realised

[chrome badger]

what i thought its 2/9 and 7/9

OB represents the full 9 parts, so if ON is 2/9, then OB would be 7/9?

[young badger]

I'm pretty sure thst usually for ratios you add them up to give you a total, which I believe is 11 and then you put the ratios over that denominator if thst makes sense so like 2/11 and 9/11.

However please do check the mark scheme and let me know if this is not the case because then I would need to brush up on my knowledge on vectors.

For all the examples I've done so far, that's how I usually do it and it seems correct.
