Connecting Math: Just for Fun #13
1. Share equally ten oranges to 12 children, with the condition to cut each orange in no more than 12 slices.

2. We have the following figures: 1, 2, 3, 4, 5, 6, 7. How many (+) "plus" signs we must write for the sum to be 100? We mustn't change the order of the figures.

Solutions:

1). 6 oranges are cut in halves and 4 oranges are cut in 3 equal parts.

2). 1+ 2+ 34+ 56+ 7= 100 (4 "+" signs)
