Chapter P.2, Problem 64E
Solution
a.
The coordinate of the points one-third and two-thirds of the way from
Given:
The numbers,
Calculation:
Note that the distance between the points a and b on the number line is
One third of this distance is,
So, the point that is one-third from a must be 2 units right of the point a . And the point that is two-thirds on the way must be 4 units right side of a .
Thus, the point that is one-third of the way is 4 and the number that is two-thirds is 6.
b.
The coordinate of the points one-third and two-thirds of the way from
Given:
The numbers,
Calculation:
Note that the distance between the points a and b on the number line is
One third of this distance is,
So, the point that is one-third from a must be
So, the point on the number line that is one-third from a is
And the number that is two-thirds from a is
Thus, the point that is one-third of the way is
c.
The coordinate of the points one-third and two-thirds of the way from a to b .
Given:
The numbers,
Calculation:
Note that the distance between the points a and b on the number line is
One third of this distance is,
So, the point that is one-third from a must be
So, the point on the number line that is one-third from a is
And the number that is two-thirds from a is
Thus, the point that is one-third of the way is
