Balance Beams 1Math brain teasers require computations to solve.
Two beams (rows of numbers) are given below. The first beam has a sum of 17; the second beam has a sum of 22. Your challenge is to balance the beams, so that the two rows have the same sum. You are only allowed to move two numbers; all of the numbers must be used in the answer.
1 3 5 8
2 4 7 9
HintThe sum of all the numbers is odd.
One of the numbers must be moved in a tricky way to make a smaller number.
AnswerMove the 9 to the top row, but as you do, turn it upside down, making it into a 6.
Move the 5 to the bottom row. Both beams now have a sum of 18.
1 3 6 8
2 4 7 5
