a)
To represent: The given letter`s position on number line in fraction or mixed fraction form.
a)
Answer to Problem 57PPS
Different letters are represented as:
Explanation of Solution
Given information:
In given number line, the distance between two given values 1 and 1.5 is 0.5,that isdivide into ten equal parts, so that each equal part on this number line is
Formula/concept used: The position of each letter after value 0.5 will be multiplied by 0.05 to get its position in decimal form and then it will be converted in fraction form.
Calculation:
A is at sixth position from 0.5, so its position is
Similarly, B is at eighth position from 0.5, so its position is
So, C is at fourth position from value 1, so its position is
So, D is at seventh position from value 1, so its position is
So, E is at second position from 1.5, so its position is
Conclusion:In fraction form, letters positions are written as:
A`s position
B`s position
C`s position
D`s position =
E`s position
b)
To write: The inequality using the position of points E and C.
b)
Answer to Problem 57PPS
The positions of points E and C form the following inequalities:
Explanation of Solution
From result of part (a), given letters are represented in fraction form as:
Out of above given fractions, E`s position is greater than position of point C, so in inequality form, it is written as:
