After a rope is folded in half and then folded in half, it is 3 meters, how long is this rope?

Fold a rope in half and then fold it in half.

Apparently get the current length.

It's the 1 4 of the original rope

And now the length is 3 meters.

This rope was supposed to be 3*4

Get the original 12 meters long.

12 meters, the length of the rope is a quarter of the original after being folded in half twice, and 3 meters after being folded in half, so it is 12 meters originally.

The first time this rope was folded in half, it was divided into two parts, and then folded in half to divide it into four parts, so if one piece is three meters long, then the rope was originally 3 4 = 12 meters long.

According to the title, a rope folded in half and then folded in half is the length of the original rope 1 4, so 3*4 = 12 meters, and the original rope length is 12 meters.

Fold it in half twice, so multiply by 4

3 m 4 = 12 m.

After a rope is folded in half and folded in half, it is 3 meters, and this rope was originally 12 meters.

12m.A rope is folded in half, and when folded in half, it is divided into four equal parts. Part length is 3m. Then the original length of my rope is 3 4 = 12m.

Fold it in half and then fold it in half, that is, divide this rope into 4 parts, so the original length of the rope is 4 3 = 12 meters.

Fold in half and then in half, the rope is shortened to a quarter of the original, so, 3 1 4 12, so the original length of the rope is 12m

12 meters. Fold it in half is one-half, and fold it in half to make it a quarter.

So, 4 times 3 meters, is exactly 12 meters.

After a rope is folded in half, it is the original 1 2, and after it is folded in half, it is the original 1 4, so 1 4 is three meters. Then the original rope length should be three meters by 4 = 12 meters.

After a rope is folded in half and folded in half, the current length is 1 8.

3 1 8 = 3 8 = 24 (m).

A: A rope turned out to be 24 meters.

When a rope is folded in half and then folded in half, a rope is divided into four sections.

3 4 = 12 (m).

The rope turned out to be 12 meters long.

Find a physical operation, you can know that the length of the fold is the original 1 4, so this rope is 12 meters long.

3 2 2 = 12 meters, folded in half and divided into two parts and then folded in half and divided into two parts, a total of four equal parts, so 3 2 2 = 12 meters.

This rope was originally 12 meters long, and when folded in half, half of the original length was divided by 4, so the original length was 3 4 12 meters.

A rope folded in half is 1 2, and then folded in half is 1 4, and it is 3 meters long, so the original rope length is 3 1 4 3 4 12 meters.

Fold in half and fold in half, it is the original 1 2x2.

3x2 2 = 12 (m).

After a rope is folded in half and then folded in half, it is 3 meters, and this rope originally had 3 4 = 12 meters?

The rope turned out to be 12 meters long.

A rope is folded in half twice to divide the rope into 4 equal sections, each section is 3 meters, and the rope is originally 12 meters long.

The rope is folded in half, and then the length of the fold becomes the original 1 2 1 2 = 1 4.

The original rope length was: 3m 1 4 = 3 4 = 12.

The rules of multiplication:

Digit alignment, from the right, use the number on each of the second spine factor to multiply the first factor, and multiply to which digit you want, and the end of the number will be aligned with which digit of the second factor.

The digits of the two digits are the same, while the digits of the two digits are complementary.

1) Take one of the two numbers respectively, and add one to the latter one, and multiply.

2) Multiply the mantissa of two numbers, (less than ten cherry dates, ten digits add 0), oral decision: head plus 1, head by head, tail by tail.

From the inscription, it can be seen that the rope is folded in half 3 times, so each section is 1 2x1 2x1 2 = 1 8, that is, 1 8, and the length of each section is 3x1 8 = meters.

Fold it in half once and multiply it by 1 2, and fold it in half 3 times to multiply it by 3 1 2, that is, each section is 1 8 of the rope length, and each section is 1 meters long.

Answer: A 3-meter-long rope is folded in half, folded in half and folded in half, each section is 1 4 of the rope length, and each section is 1 meters long.

Each section is 1 8 meters long and 3 8 meters long.

From the inscription, it can be seen that it was folded in half three times, 2 2 2 = 8, and the rope was divided into eight sections. Each section is 1 8 meters long and each section is 1 8 3 = 3 8 meters.

For this kind of problem, folding once is one negative one-part of the original two, folding twice is one-part of the negative quadratic of the original two, folding three times is one-part of the negative cubic of two, and so on, so the three-fold is the original 1 8, so the length of each section is 3 8m.

Because it was folded in half three times.

Each paragraph is one-eighth of the total length.

The actual length is 3 8 meters, that is, meters.

3 meters folded in half, that is, meters, meters folded in half, for meters, meters folded in half, for meters, for one-eighth of the original length.

A 3m long rope, folded in half and folded in half. Each section is 1 8 rope length, and each rope length is 3 8m.

Answer: After this rope is folded in half three times, the length of each section of rope is 1 8 of the total length, and the length of each section is centimeters.

Each section is 1 8 of the length of the rope, and the length of no section is 3 * 1 8 = 3 8 meters.

Answer: 1 8 (1 in 8); 3 8 (three-eighths).

Analysis: If you fold it in half once, it will be divided by 2, and three times is 2*2*2=8

So one out of eight, three out of eight for each.

3x(1 2)x(1 2)=m.

Each segment is meters long. Each segment is 1 4 of the length of the rope

It is 1 8 of the total length, and the length of each section is meters.

Each segment is one-eighth of the original and is one meter long.

Grade 2 math easy to make mistakes: A rope is 5 meters long after being folded in half 3 times, how many meters is it long?

Hello dear. We can think of it this way:

If a rope is folded in half once, it becomes 2 sections, and when it is folded in half again, 2 sections become 4 sections, and when folded in half again, 4 sections become 8 sections, so the length of a rope is 3 meters after being folded in half three times, then.

The original length should be 3 8 = 24 (m).

Hope, thank you.

Analysis: Half of the total length after the first fold, and a quarter of the total length after the second fold, that is, 3 meters, then the total length of the rope is 3 4 = 12 meters.

Because folding in half once is two sections, and folding in half twice is four sections, at this time it is known that each section is 3 meters, therefore, the length of this rope is:

3x4 = 12 (meters).

After folding in half twice, there are 4 sections, each section is 3 meters long, and the rope length is:

3x4 = 12 (meters).

There is a picture of the original covering.

2x2x2 = 8 meters.
