5 children are allowed to divide a cake with only three knives, how can they divide 50 equally

You don't need that kind of joke to be divided, I believe I'm getting closer.

There is a premise, the quality of the cake should not be too bad.

First, extend the knife side parallel to the cake and insert the tip of the knife down a short distance from the edge (not too close and not too far, control yourself, I believe)."Take control yourself"These four words should not violate the rules).

Next, the cake is rotated in a spiral shape to form a ribbon from the outside to the inside (like chewing gum used to be).

Then be careful (and it shouldn't be unrealistic) to pull the ribbon cake apart, fold it in half, and form a U-shape.

Now let's assume that the total length of the ribbon cake is 10 meters, 5 meters after folding, the second knife is 1 meter away from the bottom of the U-shape, and the third is 2 meters away from the second knife, so that there will be 5 pieces of 2 meter long sheet cake.

Method 2, albeit a bit extreme.

Find a watermelon knife, burn red in the middle, and fold the knife in half to 72 degrees, which is a circle of 1 5

Then find the center of the cake, use your finger, or something, to draw 5 lines and divide the cake in 5 equal parts (this is a basic geometry problem, it's not difficult, and you can even use a protractor).

Then you can cut it, this knife has two sides, exactly 72 degrees, exactly 3 knives.

First, make the edge of the cake into ten equal portions (just make a ha-marker), and make a mark one, two-,..Ten. Then cut one knife in one mark (all are equal parts), mark three places, and cut one knife in five marks.

There will be 4 cakes as big and 2 small ones, and 2 of the small ones together will be the same size as the big ones, you can draw a picture to see it, and I don't need to talk about it in the future.

One is slashed to death, then two are cut into quarters and divided into two other two.

First divide a circle into 10 equal parts, the upper half circle 50%, the bottom half circle 50%.

Among them, four children eat 20% and the fifth child eats 10% + 10% two pieces.

Homicide laws. With a knife.

Hack a child to death.

And then. The remaining two knives are cut horizontally and vertically in a cross row.

It is divided equally among the remaining 4 children.

Sophistry. It can be assumed that the cake is not round.

Like a five-pointed star, a rectangle, or something like that.

Scientific Law. Cut a knife horizontally and vertically in the shape of a cross in the center of the circle, and then cut a knife horizontally at the top of the cake at a thickness of 1 5. So it goes down to 4 small pieces and 4 large pieces. 4 small pieces are all given to a child, exactly 1 5;Put the remaining 4 large pieces each 4 5 * 1 4 = 1 5

That big word cutting method is not scientific.

Because there is no way to achieve the amount accurately (in only one knife.

Cut three times. and a piece of cake, five children.

for props)

Cut the cake vertically twice before killing a child! Finally, it's OK to divide the cake among the four children...

Cut into zigzags and divide into 5 portions.

Kill a child with one slash.

The simplest thing is to cut the word "big".

First cut off 1 5

Then cut the remaining 4 5 again

Put two 2 5 on top of each other. A knife.

One slash to death, two slashes scored.

This question itself is problematic, how can it be divided? Cut three knives, leave me one, and leave five copies for you.

Let a child eat less .........

Scare away a child with one knife, then cut the cake into quarters with two knives.

Analysis: 5 children, only cut three knives to divide the cake, no matter what, can not be divided, only the remaining four children can distinguish clearly.

One of the obvious features of this kind of wordplay is that the questions are very ordinary, but the answers are very annoying or hilarious, and sometimes, they can play an indirect role in swearing. Once cracked, it makes people squirm. So asking about brain teasers also has the effect of adjusting the atmosphere at a party.
