This proved quite a difficult challenge for many of you. First of all a big well done to Abbas, Mia, Dev and Luca for having a go. Yasmin was the only one who got both answers correct. Here is her answer:
Yasmin Kudrati-PlumberMar 19 (9 days ago) My strategy was to start backwards and continue from there, Andy had 24 which was 2/3 of what he shared with Sam so 14 divided by 2 is 7 and 7 plus 14 is 21 which is half of what the other children took, 21 plus 21 is equal to 42 and 1/3 plus 1/6 is 1/2 so 42 is equal to 1/2 so 42 plus 42 is the answer, there were 84 marbles in the bag before it broke. The answer to the next part was 84 take away 14 which is 70 so the number of marbles that he gave away or lost was 70 and that would be as a fraction 10/12. I hope I am right and I think this was a good challenge for homework. A magician took a suit of thirteen cards and held them in his hand face down. He took the top card off the pile and put it at the bottom , saying 'A' as he did it. He took the next card and said 'C' as he put it at the bottom. He took the next card and turned it over, saying 'E' as he did it - and the card was an ACE! He carried on with the letters T-W-O and as he said the 'O' he turned over the card and it was a TWO! He carried on with T-H-R-E-E, the FOUR and so on, and in each case as he said the last letter of the name he turned over the card and everyone was amazed that he had predicted what it would be. How did this work? |
