Concept explainers
a)
To convert: The decimal numbers of the given table in fractional form.
a)
Answer to Problem 64STP
Each decimal in simplest fraction form is as follows:
Explanation of Solution
Given information: A table that shows the method of transportations and total portion of students (in decimal form), using these methods.
Concept used: Given decimal values are written in fraction form by removing its decimal sign and dividing them by 100 and then by converting them in simplest form. Further by comparing the numerators, with denominator 100, given decimal numbers are put from least to greatest.
Calculation: Change decimal values in simple fraction form as shown below:
Conclusion: By above calculation, it is cleared that each decimal in simplest fraction form is as follows:
b)
To list: The methods of transportation in order from least to greatest.
b)
Answer to Problem 64STP
List of methods of transportations from least to greatest is:
Others, bicycle, walk, car, bus
Explanation of Solution
Given information: A table that shows the method of transportations and total portion of students (in decimal form), using these methods.
Concept used: First write the given decimal numbers in ascending order and then put methods of transportation, represented by these number in the same order from least to greatest.
Calculation: Write given decimal number in ascending order, from least to greatest as:
Conclusion: By above sequence, it is cleared that methods of transportations representing above decimal number, in ascending order are:
Others, bicycle, walk, car, bus
c)
To find: The methods of transportation that is used by most students to get to school.
c)
Answer to Problem 64STP
Bus is used by most of the students to get to school.
Explanation of Solution
Given information: A table that shows the method of transportations and total portion of students (in decimal form), using these methods.
Concept used: First write the given decimal numbers in ascending order and then put methods of transportation, represented by these number in the same order from least to greatest.
Calculation: Write given decimal numbers in ascending order as:
Conclusion: By above sequence, it is cleared that greatest number is 0.4 that represents method of transportation as BUS, so bus is mostly used by the students to get the school.
