Hi,
I have got the answer to this question and I cannot understand why it is the chosen one:
"Vladimir wants to have some cake left over for himself after he distributes a share to each of his 8 friends.
Which of these options, of what fraction of a cake to give each friend, will allow this?
1) 12%
2) one seventh
3) 0.14
4) two ninths
5) 3/20
the answer is supposedly 12% - because 12 fits in "8" times in 100 (one whole cake) + leaving .33 remainder (100 divided 12 - 8.33)
so Valdimir friends gets 8 cakes and he get .3
Is this the correct concept being explained to my kid - what I am struggling to understand and explain is the .33 - how about the remaining .63 as that would make the whole cake.
Who would get the .63 bit?
i some how got 2/9ths as the answer and now I just cannot back track on how I got this...
please help.
thanks,
saf
