Mom wants to take five ice creams to my brother and me, how many ways are there to divide them?

Your mother is going to give you and your brother five ice creams, there are several divisions, the first division is for the sake of fairness, your mother keeps one ice cream for herself, and you and your brother each have two ice creams, so it's fair to both of you. The second division is that you have three ice creams, and your younger brother has two, because ice cream is a cool thing after all, and the older you eat, the less harmful it will do to your body. The third division is that you have two ice creams and your brother has three ice creams, because your brother is small, you can eat one more.

Your mom won't split into 1 and 4 because it's so unfair. It will eat too much, which is relatively cold to the body and has no benefit.

Four types: the first one: one for me and four for my younger brother.

The second type: I have two and my brother has three.

The third type: I have three and my brother has two.

Fourth: I have four and my brother has one.

Since it's for me and my brother, there is no such thing as one side being zero, but in real life, it is recommended to choose the first two methods, because the latter two may cause a family storm...

There are four ways to do this. One, four, two, three, four, one, three, two, these are the four divisions.

Solution: Of course, there is only 1 division, 1 for each of the three of you, and the remaining 2 for the refrigerator.

Satisfied.

This can be divided into one and four, two and three, right?

How many ways are there to get 5 ice creams for you and Titi? That's of course 5 ways.

The first time: choose 4 from 5 ice creams, divide them into two equal portions, 2 pieces each, and place them at both ends of the balance scale, if the balance scale is balanced, then the ice cream is 155 grams without taking it, if the balance scale is not balanced;

The second time, put 2 ice creams at the higher end of the scale on both ends of the scale, and the ice cream at the higher end is 150 grams;

A: At least the second time you will be able to find ice cream weighing 155 grams

Now put two on the left and right sides of the scale, and if you balance the remaining one, it will be 155kg. If you don't balance the balance and sink downward, there must be 155kg of ice cream on either side of the scale, and on which side is down, there will be 155kg of ice cream. So, weigh it at least twice.

At least 1 time, that is, exactly 1 is heavy, OK.

Up to 2 times, you can find out.

The first time: choose 4 from 5 ice creams, divide them into two equal portions, 2 pieces each, and place them at both ends of the balance scale, if the balance scale is balanced, then the ice cream is 155 grams without taking it, if the balance scale is not balanced;

The second time, put 2 ice creams at the higher end of the scale on both ends of the scale, and the ice cream at the higher end is 150 grams;

A: At least the second time you will be able to find ice cream weighing 155 grams

Weigh at least twice. Divide 5 ice creams into 3 portions. i.e. (percolation 2, 2, 1), first put 2 on each side of the balance, if the balance is balanced, the remaining one weighs 155 grams.

If it is not balanced, then 155 grams of ice cream in the heavier portions. Then the brother shouted that the heavier one was put on each side of the scale, and the heavier one was 155 grams of envy ice cream.

It's better to write the essay yourself, after all, you can't copy it during the exam!

Respect my sister's wishes, my sister is willing to share my sister's willingness to accept the best, if my sister is unwilling, I personally think that it should not be forced or forced, and it can't be because my sister finished eating first, my sister should be humble to what originally belonged to her. Maybe my sister loves this ice cream more, and wants to taste it slowly, and forcing my sister to share it will cause my sister to feel uncomfortable or unfair, and to put it seriously, it may even encourage my sister's behavior without a sense of boundaries, and I can also ask for my sister's things. When I was a child, it was ice cream.,Maybe it's a boyfriend when you grow up.。。。

Therefore, I personally think that sharing or not depends on my sister's wishes, and respect her. It's good for the two children, the elder sister learns to protect what belongs to herself, and the younger sister learns to accept that if she loses, she can't take away the love of others.

If my sister is willing to share, I will share, if my sister is unwilling, don't share, although it is said that the small one should be allowed, but these are two, both of them are the same, and my sister has no reason to want my sister after eating herself, so it is unfair to my sister, and it will imperceptibly affect the values of my sister and sister,

It stands to reason that it should be one for one person, but the sister doesn't necessarily have to share it with the sister after the sister eats it, mainly because the sister herself is voluntary.

No, my mother bought two ice creams, one for each person, and your sister finished eating it, she ate it too quickly, so why do you want it? Unless it's your mom who is eccentric.

No need.,Sharing is in the case of my sister not having it.,Since you're done eating, it's fast to eat.,There's no need to share.。

Your mother treats everyone fairly, everyone gives one, I don't think it's necessary to share, it's just that your sister eats faster, and you eat more slowly.

You can share it, because my sister can share it with my sister.

The sister should be allowed to decide that she has the right to make a choice, there is one for each of the two children, why should the sister share it after the sister eats it, this is too unfair to the sister.

It shouldn't be because mom only bought two ice creams, it should be one for each person.

Yes, it's all the family who is buying after eating.

It can be for it or not, it can be, she is your sister, it can't be, the big one should let the small one.

The big and the small should be treated equally. My sister finished eating the ice cream, and by the way, she finished eating it every day, so why did her sister give it to him?
