Answer :
Work backwards. If there were 14 at the end, then multiply this by 3/2 because 2/3 of the marbles were given to Sam. so 14 times 3/2 is 21. There were 28 total because if you add 1/3 to 1/6 you get 1/2. So they they lost 1/2 of the marbles and got 1/4 of the original amount back, which was 21.
So the original number was 28. Hope this helps!
So the original number was 28. Hope this helps!
I'm PRETTY sure you have to do......
14 X 1/3 = 4.6
14 X 1/6 = 2.3
14 divided by 1/2 = 7,
- 1/3
so
4.6 + 2.3 + 7 = a
a - 1/3 = b
b = the answer
I'm PRETTY sure!!!!
