Problem number 12. A number is written on each petal of two flowers. One petal is hidden.  The sums of the numbers on the two flowers are equal. What number is written on the hidden petal? A, 0. B, 3. C, 5. D, 7. E, 1.  To solve this problem, we are going to add all the numbers on each flower together.  Then we will subtract our two answers and the number that we get will be the number that is missing. Because we know that the sums should be equal.  7 plus 3 is 10. 9 plus 1 is 10. And then plus 5 is 25. And then on the other flower, 6 plus 4 is 10. 8 plus 2 is 10.  So the answer for that one is 20. Now 25 minus 20 equals 5. So that means our answer is C, 5.
