If they balance out, then 3 is the heavier one. If the right side is heavier, then we know that either 4, 5 or 6 is the heavier ball. Weigh {4} on the left and {5} on the right. By doing this we will know if 4 or 5 is heavier.
How do you find the heaviest ball?
To figure out which one it is, weigh any two against each other — say, A versus B. If one or the other is heavier, then you’ve found your answer. If the scale balances, then you know the heavy ball is C.

How would you find the heaviest ball bearing from 9 ball bearings given a scale?
Divide the 9 balls into 3 groups of 3. Compare the weight of two of those groups. The heavier group should then be obvious, it will either tip the scales, or, if the scales stay balanced, then it is the group you didn’t include.
Is the 8 ball heavier in pool?
No, the cue ball is typically not smaller. If the cue ball is a different size than the object balls, it will be larger and not smaller. This is usually the case when playing on a bar box or coin-op table. Using the same pool balls over time can also make them smaller and lighter.
How will you weigh 9 marbles 3 times on a balance scale to find the heaviest one?

How can you identify a heavier ball from 9 similar looking balls?
Split the balls into groups of three, compare two of the groups. If the sets balance then the heavy ball is in the third group, otherwise it is in the group left out. Whichever it is, take two balls from that group to weigh. If they balance, you know it is the third ball, if they don’t, you have the heavier ball.
