PPT on finding defective products, part 2: knowledge explanation

There are 3 bottles of calcium tablets, one of which is missing 3 tablets.

Can you manage to find it out?

It can be weighed using a scale.

Exploration point: Use a scale to find 1 defective item among 3 items.

Weighing method: Place 1 bottle in the trays on the left and right sides of the balance.

If the scales balance, then the remaining bottle is defective.

If the scale is unbalanced, the lighter bottle is the defective.

Tip: Although the balance only has 2 trays, the third item outside the tray also participates in the comparison, so the balance can compare the masses of 3 items at one time.

One of the nine parts is a defective product (the defective product is heavier). If you use a balance to weigh it, how many times can you weigh it to ensure that the defective product can be found?

Finding defective products PPT, the third part: knowledge summary

01 In life, there are often situations where an item of different quality (lighter or heavier) is mixed among some seemingly identical items. We need to find a way to find it. For problems like this, we It's called "looking for defective products."

02 Use the principle of balance balance to "find defective products" and find 1 defective product among 3 items. It needs to be weighed at least once to ensure that the defective product is found.

03The best strategy for finding multiple defective products is to divide the object into 3 parts, and the second is to try to keep the quantity of each part as even as possible.
