A very interesting question 5, a very interesting question

It doesn't make sense, there is no scientific basis.

Because that person has rheumatism.

15 first buy 10 peaches for one yuan, after eating 9 peach hu for 3 peaches, and then use these three peach hu to exchange for one peach. When you're done, you'll have two peach beards in your hands. You can exchange these two peach hues for one peach.

Give him the peach beard after eating. You don't have anything left, and you don't owe anyone else.

A total of 10 + 3 + 1 + 1 = 15.

First of all, eat ten yo and ten cores for one dollar. Swap three cores for a peach, so that there are 8 cores, and then use three for a peach, and then use three for a peach, which is 4 cores, and then use three for a peach, and there are two cores left, first give two for a peach, and give him the core after eating the peach. So it's 10+1+1+1+1+1=15.

14 spend nine cents to buy nine, the kernel you eat can be exchanged for 3, plus the last dime, a total of 4 Hu, four Hu can be exchanged for 1 peach, and finally there are 2 cores left

I ate a total of 9 + 3 + 1 + 1 = 14

1/2+1/3+1/9=17/18

It is good to divide the 17 gifts according to 18, the eldest daughter: 18 1 2 = 9 (pieces).

Second daughter: 18 1 3 = 6 (pcs).

Youngest daughter: 18 1 9 = 2 (pcs).

9+6+2=17 (pcs).

The eldest daughter has 9 daughters, the second daughter has 6 daughters, and the youngest daughter has 2 daughters.

It's not that hard to talk about, but that's it! Or is it still very easy to say, this is a very different feeling, this nature and everything is a different feeling.

Not like that.

3x9=27.Of these 27, the boss gets 25, and the service shouter gets 2.

Coupled with the 1 in the hand of each year, the total is 3, 1x3=3, then 27+3=30

Thank you, Zakino.

1 Take 6 balls first, 3 on each side, and if balanced, then check the remaining two; If it is not balanced, Kong Bixiang can take out 2 more of the 3 balls for testing.

2 The key is who is active and who is passive.

3 When the bottom of the glass is facing up, there is no external force, and by gravity alone, can it be immersed in water?

4 The sound becomes louder because the power of the sound becomes larger, and the vibrating kinetic energy and elastic potential energy in the tuning fork are only converted into sound energy more quickly, and the energy is still conserved.

5 Isn't it supposed that both balls will not sink, if they are all immersed in water, then the buoyancy is greater than the gravity, and they will float, and they will eventually float. (From the inscription, the steel ball should be hollow) fighting.

6 On the right side of the balance (adjusted) there is a bottle of Huishizi, a few flies are placed in the bottle, when the fly stops at the bottom of the bottle, the balance is just balanced, so when the flies are flying in the bottle, can the balance still be balanced? It can still be balanced, because the flight in it is also due to the buoyancy of the air, so whether it is flying or stationary, it is balanced, I think the balance is difficult to balance, because the fly is "flying around", so its state is changing all the time, and it should not be counted as a state of equilibrium.

You're really good at counting, 6 at a time.
