large yellow cubes huh

#

well

runic mauve
#

make some variables
a = smallyellow, b = largeyellow, c = largered
a/(b+c) = 4/7
c/(a+b) = 3/5

lemme see what i can do wi that rq

runic mauve
#

alright so there's not enough information to find a,b,c

#

however you can notice, that if you multiply a valid solution, by 2, ex. (a,b,c) -> (2a,2b,2c) all the ratios still hold

#

that means you can scale the triple by any positive number, so just say b = 1 arbitrarily

#

then you can solve for a,c

dusk leaf
#

what would you get as the answer if you solved it

#

i can probably find the working easier if i know the answer

runic mauve
#

doubt

dusk leaf
#

trust

#

my mind is weird as fuck

runic mauve
#

a/(1+c) = 4/7
c/(1+a) = 3/5

dusk leaf
#

is it 39/88

runic mauve
#

for either a or c

dusk leaf
#

oh shet

show your steps

#

still no, but closer

#

so you have 7a = 4 + 4c
5c = 3 + 3a?

#

definitely a bit annoying to solve
a = (5/3)c - 1
7(5/3)c - 7 = 4 + 4c
35c - 21 = 12 + 12c
23c = 33

for it to be the least possible, take the LCM
small cubes = 4x
large cubes = 7x
red cubes = 3y
yellow cubes = 5y
4x+7x = 3y+5y
11x = 8y
LCM(11, 8) = 88
so least possible total number of cubes is 88
am I correct?

ok

runic mauve

yep

dusk leaf
#

@runic mauve whats the answer

runic mauve

given there are 88 total cubes, can you figure it out?
