If a divided by B equals 0.4, B divided by a equals 1, and 0.4 equals 2.5 ()

If a divided by B equals 0.4, B divided by a equals 1, and 0.4 equals 2.5 ()

Right is the true proposition
The formula is as follows:
A / b = 0.4
Side by side: B / A
Then: 1 = 0.4 * B / A
So: B / a = 1 / 0.4 = 2.5

To build a 1500 meter long road, 14% of the whole project will be completed in the first week, 25% in the second week, and how many parts of the whole project will be completed?

1-14-25 = 34 − 25 = 720. Answer: the 720 of the whole project will complete all tasks

A rope is 20 meters long. For the first time, a quarter of the length of the rope is used. For the second time, the remaining two fifths are used. What is the remaining part of the rope?

After using a quarter of the length of the rope, there are still 15 meters left. After using the remaining two fifths for the second time, there are still 15-15 * 2 / 5 = 9 and 9 / 20 of the length of the rope

The wire, which is two fifths of a meter in length, is divided into four sections. What is the length of each section? What is the length of each section?

It is divided into four sections. Of course, each section is one fourth of the total length. Two fifths multiplied by one fourth equals one thirtieth

The 4-meter-long wire is divided into 5 sections. How many parts of the length of each section, how many parts of the length of each section, and how many parts of the length of each section?

The 4-meter-long wire is divided into 5 sections, each of which is a fraction of the total length,
1 △ 5 = 1 / 5
The length of each segment is a fraction of a meter,
4 △ 5 = 4 / 5
What's the length of each segment?
4 △ 5 = 4 / 5 (m)

Divide the 4 / 5 meter long wire into 4 sections, each section is [] meters long, and the length of each section is a fraction of the total length

Divide the 4 / 5 meter long wire into 4 sections, each section is [1 / 5] meter long, and the length of each section is one fourth of the total length

Divide a 2-meter-long wire into 5 parts. What is the total length of each part? How many meters is the length of each part?

1/5 5/2m

The 5 / 3 meter long wire is divided into 6 sections, each section is () meters long, and each section accounts for a few parts of the total length

Divide the 3 / 5 meter long wire into 6 sections, each section is (1 / 10) meters long, and each section accounts for 1 / 6 of the total length

Two fifths of 20 meters is 56 meters?

20×2/5÷56=1/7
Two fifths of 20 meters is one seventh of 56 meters

2 / 5 of 20 meters is what fraction of 56 meters?

It's 20 × 2 / 5 / 56 = 1 / 7
