What Point on the Number Line is 1/5 of the Way from -7 to 17?

Understanding the Problem

To find the point on the number line that is 1/5 of the way from -7 to 17, we need to calculate the distance between -7 and 17, and then find 1/5 of that distance. This will give us the point on the number line that is 1/5 of the way from -7 to 17.

Calculating the Distance

The distance between -7 and 17 can be calculated by subtracting -7 from 17. This gives us:

17 - (-7) = 17 + 7 = 24

So, the distance between -7 and 17 is 24 units.

Finding 1/5 of the Distance

To find 1/5 of the distance, we need to multiply the distance by 1/5. This can be done by dividing the distance by 5:

24 ÷ 5 = 4.8

So, 1/5 of the distance between -7 and 17 is 4.8 units.

Finding the Point on the Number Line

To find the point on the number line that is 1/5 of the way from -7 to 17, we need to add 4.8 units to -7. This gives us:

-7 + 4.8 = -2.2

So, the point on the number line that is 1/5 of the way from -7 to 17 is -2.2.

Conclusion

In conclusion, the point on the number line that is 1/5 of the way from -7 to 17 is -2.2. This can be verified by calculating the distance between -7 and 17, and then finding 1/5 of that distance. The correct answer is A. [-2.2].

Understanding the Concept

This problem requires an understanding of the concept of distance and fractions. The distance between two points on a number line can be calculated by subtracting the smaller number from the larger number. A fraction of the distance can be found by multiplying the distance by the fraction. In this case, we need to find 1/5 of the distance between -7 and 17.

Real-World Applications

This concept has real-world applications in various fields such as engineering, physics, and architecture. For example, in engineering, the distance between two points on a graph can be used to calculate the length of a cable or a wire. In physics, the distance between two points can be used to calculate the time it takes for an object to travel between those points. In architecture, the distance between two points can be used to calculate the length of a building or a bridge.

24 ÷ 5 = 4.8

So, 1/5 of the distance between -7 and 17 is 4.8 units.

Q: How do I find the point on the number line that is 1/5 of the way from -7 to 17?

A: To find the point on the number line that is 1/5 of the way from -7 to 17, we need to add 4.8 units to -7. This gives us:

-7 + 4.8 = -2.2

So, the point on the number line that is 1/5 of the way from -7 to 17 is -2.2.

Q: What if I want to find 1/3 of the distance between -7 and 17?

A: To find 1/3 of the distance, we need to multiply the distance by 1/3. This can be done by dividing the distance by 3:

24 ÷ 3 = 8

So, 1/3 of the distance between -7 and 17 is 8 units.

Q: How do I find the point on the number line that is 1/3 of the way from -7 to 17?

A: To find the point on the number line that is 1/3 of the way from -7 to 17, we need to add 8 units to -7. This gives us:

-7 + 8 = 1

So, the point on the number line that is 1/3 of the way from -7 to 17 is 1.

Q: What if I want to find 2/5 of the distance between -7 and 17?

A: To find 2/5 of the distance, we need to multiply the distance by 2/5. This can be done by multiplying the distance by 2 and then dividing by 5:

24 × 2 = 48 48 ÷ 5 = 9.6

So, 2/5 of the distance between -7 and 17 is 9.6 units.

Q: How do I find the point on the number line that is 2/5 of the way from -7 to 17?

A: To find the point on the number line that is 2/5 of the way from -7 to 17, we need to add 9.6 units to -7. This gives us:

-7 + 9.6 = 2.6

So, the point on the number line that is 2/5 of the way from -7 to 17 is 2.6.

Q: What if I want to find 3/5 of the distance between -7 and 17?

A: To find 3/5 of the distance, we need to multiply the distance by 3/5. This can be done by multiplying the distance by 3 and then dividing by 5:

24 × 3 = 72 72 ÷ 5 = 14.4

So, 3/5 of the distance between -7 and 17 is 14.4 units.

Q: How do I find the point on the number line that is 3/5 of the way from -7 to 17?

A: To find the point on the number line that is 3/5 of the way from -7 to 17, we need to add 14.4 units to -7. This gives us:
