A rectangular piece of paper, folded in half three times, how many fractions of the paper is in each

Fold a rectangular piece of paper in half 3 times, one of which is 1 8 of this paper.

The process is as follows:

1) A rectangular piece of paper is folded in half 1 time, and 1 of the copies is 1 2 of this paper.

2) A rectangular piece of paper is folded in half 2 times, and 1 part of it is 1 2 1 2 = 1 4 of this paper.

3) A rectangular piece of paper is folded in half 3 times, and 1 part of this paper is 1 2 1 2 1 2 = 1 8.

A square of paper is folded in half 3 times, and each piece is its 1 8.

Fold it in half 3 times, each part is 1 2x1 2x1 2 = 1 8.

Multiplication and division. 1. The fraction is multiplied by an integer, the denominator remains unchanged, the numerator is multiplied by an integer, and finally the offer score that can be reduced.

2. Multiply the fraction by the fraction, multiply the numerator by the numerator, multiply the denominator by the denominator, and finally the offer score that can be reduced.

3. The fraction is divided by an integer, the denominator remains unchanged, if the numerator is a multiple of the integer, the numerator is divided by the integer, and finally the offer score that can be reduced to a fraction.

4. The fraction is divided by an integer, the denominator remains unchanged, if the numerator is not a multiple of the integer, then multiply this fraction by the reciprocal of the integer, and finally the offer score that can be reduced.

5. The fraction is divided by the fraction, which is equal to the reciprocal of the dividend multiplied by the divisor, and the last offer point that can be reduced.

1 in 8. Analysis: 1. Fold in half 1 time, indicating that it is divided equally: 1 2 = 2 (parts).

2. Fold it in half 1 more time, indicating that it is divided equally: 2 2 = 4 (parts).

The fold is divided in half, indicating that it is divided into equal parts: 4 2 = 8 (parts).

4. Get 1/8 of this square.

Notes on scores:(1) The denominator must not be 0, because the denominator is equivalent to the divisor. Otherwise, the equation cannot be held and the numerator can be equal to 0 because the numerator is equivalent to the dividend.

It is equivalent to 0 divided by any number, regardless of the denominator, the answer is 0.

2) The numerator or denominator in the fraction cannot be an irrational number (such as the square root of 2) after being reduced, otherwise it is not a fraction.

It's straight to the point and focused.

Fold a rectangular piece of paper in half three times in a row, and each copy is 1/8 of the paper.

Equation according to the title:

1x1/2x1/2x1/21x1/8

The first time is a half, the second is a quarter, and the third is an eighth.

2 to the nth power is OK, and it can be calculated by folding a few times.

A rectangular piece of paper is folded in half three times, the first time is 2 parts, the second time is 2 2 parts, and the third time is 2 2 parts, that is, 2 parts, then the paper is divided into 2 parts, one of which is 1 2 of this paper.

A fold is divided into 2 small rectangles;

Two-fold is to divide the small rectangle into 2 equal parts and the 2 equal parts into smaller rectangles; That is, a small rectangle divided into 2 and 2 equal parts.

3 fold, that is, the small rectangle of 2 2 equal parts is divided into 2 equal parts, that is, 2 2 2 = 8 equal parts.

So after folding it three times and then opening it, the paper is divided equally.

8 aliquots. One of them is one-eighth of this paper.

Fold in half once: one becomes two. Fold in half twice: two becomes four.

Fold in half three times: four to eight.

The paper is folded in half three times and divided into eight equal parts, one of which is one-eighth of the paper.

Summary. After folding a rectangular piece of paper in half four times in a row, a small rectangle formed by the creases is formed, and each small portion accounts for 1 16 of the rectangular paper.

Fold a rectangular piece of paper in half 4 times in a row, and how many fractions of the rectangular paper does each small portion occupy? What about folding it in half 5 times?

After folding a rectangular piece of paper in half four times in a row, dig a small rectangle into a small rectangle according to the crease shape, and each small portion occupies 1 16 of the rectangular loose paper.

If you fold it in half again, that is, in the case of folding it five times, then it is 1 32 pro, which is the number of copies formed by folding in half.

A rectangular piece of paper of two square decimeters is folded in half three times, with an average of how many square decimeters each share is, and each part accounts for a few points of this paper.

Hello, your question will be answered immediately, please don't rush.

Please hurry. Hello, I'm glad to answer for you: the average copy is a square decimeter of the stool bridge, and each copy accounts for one-eighth of this paper.

The solution is as follows: fold the jujube three times, a total of eight parts. Fold it n times in half, which is the nth power of 2.

The average copy is 2 8 = square decimeters, a total of eight parts, each part of the paper occupies one-eighth of the paper.

Do a thousand hu defeat paper crane pants tremble.

Used 1 5, the rest of the friends to occupy this piece of paper:

The paper was divided into 8 equal parts, each being one-eighth of it.

The analysis process is as follows:

Fold a rectangular piece of paper in half 3 times, as shown in the figure below

Fold it in half once, and the rectangle is divided into two equal parts.

Fold it in half twice, and the rectangle is divided into 2 2 = 4 parts of equal area.

Fold it in half three times, and the rectangle is divided into 2 2 2 = 8 equal parts.

Then each serving is its: 1 8 = 1 8.

Fold a rectangular piece of paper in half 3 times, and divide the rectangular piece of paper into 2 2 2 = 8 parts, then each part is its 18

Fold a rectangular piece of paper in half three times and open it again, and the paper is divided into 8 equal parts, each of which is one-eighth!

Fold a rectangle in half 3 times, and then open 8 pieces, which is 1 molecule 8 of a piece of paper.

Fold it in half 3 times, and the paper is divided into 8 parts, each of which is 1/8th of it.
