4 1/5÷2/3

express your answer as a mixed number in simplest form

6 3/10

Step-by-step explanation:

6 3/10

Step-by-step explanation:

Write the mixed numbers as top heavy fractions:

4 1/5 = 21/5

Meaning the question is 21/5 ÷ 2/3

Now use the SameKissFlip method to convert it to a multiplication (kep the same fraction the same, change ÷ to x, and flip the second fraction)

21/5 x 3/2

Solve

21/5 x 3/2 = (21x3) / (5x2) = 63/10

Now convert back to a mixed number

63/10 = 6 3/10

Step-by-step explanation:

Given

See question for data

Solving (a):

The scale used is an ordinal scale.

Ordinals scale uses hierarchy arrangement and the data can be arranged as:  

The variable of the delivery performance is qualitative because it is non-numerical  

Solving (b): Frequency table

From the table, we have:

So, the frequency distribution table is:

Solving (c): Frequency table.

To do this, we add another column (Relative Frequency) to the above table.

The relative frequency is calculated as:

So, we have:

So, the frequency distribution table is:

Solving (d & e): See attachment 1 for bar chart & attachment 2 for pie chart

Solving (f):

From the question, we understand that the object is to return 99% early or on time and never to lose a package.

The analysis is as follows:

Early and On-Time (ET) packages

Lost packages

From the above analysis, we can see that 87.4% of the packages were delivered early enough and 2.30% were lost.

The fraction of packages delivered early can be improved and the fraction of lost packages can be reduced by exploring the chances of taking alternative routes when possible.
