ok so
this question is quite tricky but i think i have a way of working it out
if you still need help
i realised that there are more than 5 coins so the only way to get 1/5 of something is if there is it a multiple of 10
so i said the total amount of coins is 10
so 1/5 of 10 is 2
nw
So then
carry on
There are 2 pennies
And the remainder is 48
So i have to get 48 with the 8 remaining coins i can use
So i got 10p 10p 10p 10p 2p 2p 2p 2p
yep looks good
how were u gonna do it
well so thats what i did
but i can show you that
15 and higher definitely dont work
if thats something youre interested in knowing
ok so as you said the number of coins is a multiple of 5
and i basically did what you did for when its 10 coins
now if we think about 15 coins
wait i might have made a mistake
lol it's fine
i wrote down "average coin < 2" but i think that was my brain malfunctioing
remember this
ofc
how do i close this question
i think you just underline all the coins listed
do /solve
