lets say volume of P is 100, so volume of Q is 50% more, 100 x 1.5 = 150
volume of R is 50% more than Q

#

so volume of R = volume of Q x 1.5 = 225

#

volume of P is 100, volume of R is 225

#

so P = 100/225 R -> P = 4/9 R

Thx bro

#

But why do you times it by 1.5

twilit niche
#

50% more

#

means 50% increase

warm abyss
#

Sorry I’m not sure how to times percentages

twilit niche
#

u cant times percentages

#

which is why you convert them into decimals

#

So how do you get 50% into 1.5

hot scroll
#

or minus it from 1 if it says decrease

twilit niche
#

50% increase is 1 + 0.5 -> 1.5

warm abyss
#

Ahh I see

twilit niche
#

50% decrease is 1 - 0.5 -> 0.5

warm abyss
#

Then you do 100* 1.5

#

increasing maths grade boundries 1 step at a time

warm abyss
#

And repeat it to get 225?

hot scroll
#

uh huh

warm abyss
hot scroll
#

or you could do 1.5* 1.5 = 2.25
100 * 2.25 = 225

Ok

#

Thanks

#

Wait can I ask 1 more question?

hot scroll
#

yh

#

go ahwad

warm abyss
#

Why do you assume that the volume of the original sphere (p) is 100cm^3

twilit niche
#

you can assume it to be anything

#

i just did 100 because its easy to work with

#

the formal way would be to let the volume of P be x

#

but i didnt wanna confuse u

warm abyss
#

Ahh ok

#

It’s fine
