Choose the division equation that represents the fraction shown.

one fourteenth = ________

A) 1 ÷ 14 = ________
B) 14 ÷ 11 = ________
C) 13 ÷ 14 = ________
D) 14 ÷ 13 = ________

Answers

Answer:

your answer is gonna be "A" if you want to type 1/14 into the calculator.

The value of expression one fourteenth = A) 1 ÷ 14

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the expression of one fourteenth

A negative divided by a negative is positive, then;

one fourteenth = 1/14

1 ÷ 14

Therefore, The value of 1 ÷ 14 = 1/14.

The guidance office at a high school surveyed their 12th grade students to know in which of four states they would prefer to live in after highschool. The results are summarized in the tso way frequency table below.

Which two-way table accurately represents the relative frequency for the whole table in this situation?

Answers

Hence, the two way frequency table is:

Action Drama Comedy total

Highschool 26/128=0.20 14/128=0.11 22/128=0.17 0.48

College 20/128=0.16 28/128=0.22 18/128=0.14 0.52

----------------------------------------------------------------------------------------------------------

total 0.36 0.33 0.31 1

Step-by-step explanation:

" When a two-way table displays percentages or ratios (called relative frequencies), instead of just frequency counts, the table is referred to as a two-way relative frequency table " .

We are given a table or data as:

Action Drama Comedy Total

Highschool 26 14 22 62

College 20 28 18 68

------------------------------------------------------------------------------------------------------------

Total 46 42 40 128

The total number of students in all the categories and classes are: 128

Hence the two way frequency table is constructed by dividing all the frequencies by the total number of students i.e. 128.

Action Drama Comedy total

High school 26/128=0.20 14/128=0.11 22/128=0.17 0.48
