2/5 divided by 1/4 as a fraction

Answers

Answer:

Step-by-step explanation:

2/5 divided by 1/4 is which (2/5)/(1/4) is  equal to fraction 8/5

The given statement "2/5 divided by 1/4 as a fraction"

It can be written as in mathematical form as (2/5)/(1/4)

To solve 2/5 divided by 1/4 as a fraction,

Multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of 1/4 is 4/1.

So, we have (2/5) ÷ (1/4) = (2/5) x (4/1).

Multiplying the numerators and denominators gives us

(2x4) / (5x1) = 8/5.

Therefore, 2/5 divided by 1/4 is equal to 8/5.

1. 4/3 and 1 1/3 because they are equivalent to each other
2. 1 & 2/3 because it is only one third away and the others are two thirds away
3. 1 & 1/2
4. 3
5. 1

Answer:

1. 4/3, and 1 & 1/3   2. 1 & 2/3    3. I D K.    4. 3

5. 1

Step-by-step explanation:

1. because 4/3 is the same as 1 & 1/3, they are the same because if you take the 4 and make it a 3, it is 1 whole, and then you put 1/3 at the end, because the is still a left over 1/3.    2. I know this because 2/3 is bigger than 1/3, and 4/3 is equal to 1 & 1/3.

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in hour. At the airport, they exited the car and walked for hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.
Answer the following questions about kileys trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that kiley is at rest.
In this task you will write the ratio of miles to hours for each leg of kileys trip. You will then express the ratio as a decimal number. Next you will find the unit rate in miles per hour for each leg of the trip.

A mine worker discovers an ore sample containing 500 mg of radioactive material. It is discovered that the radioactive material has a half life of 1 day. Find the amount of radioactive material in the sample at the beginning of the 7th day.

Answers

Answer:

7.8125 or 7.8

Step-by-step explanation:

[tex]gm=(1/2)^{n-1}[/tex]

[tex]gm=500 (1/2)^{ 7- 1} \\gm= 500 (1/2)^{6}[/tex]

= 7.8125 or 7.8

The amount of radioactive material in the sample at the beginning of the 7th day is 3.906 milligram.

What is Half life of an Element?

Half life of an element is the time taken by a radioactive substance to break down into half the quantity of the initial quantity.

In other words, we can say that it is the time for an element to disintegrate half of it's atoms.

Given that,

Half life of radioactive material is 1 day.

Initial amount of the substance = 500 mg

At the beginning of the first day, there will be 500 / 2 = 250 mg os substance.

Taking the first term as 250 and the common ratio as 1/2, we can consider this as a geometric sequence.

nth term of a geometric sequence = a rⁿ⁻¹, where a is the first term and r is the common ratio.

At the beginning of seventh day,

Amount of radio active substance = 250 (1/2)⁷⁻¹ = 3.90625

Hence the amount at the beginning of seventh day is 3.906.
