Lesson Steps

Step Type Explanation Answer

1

Problem

5, 7, 10, 17, and 16. The mean of the list of numbers above is what fraction of the sum of the five numbers?

2

Step

Given data

5, 7, 10, 17, and 16

3

Step

To Find the sum of the numbers

5 + 7 + 10 + 17 + 16 = 55

4

Formula:

Formula for mean

Mean = \$("Sum of numbers")/("Number of numbers")\$

5

Step

​Find the mean of the numbers

\$"Mean" = 55/5 = 11\$

6

Step

The sum of 5 numbers is 55.

7

Step

Find the fraction of the mean of the list to the sum of the five numbers

Fraction = \$("Mean of the list")/("sum of the five numbers")\$

\$"Fraction" = 11/55 = 1/5\$

8

Step

So, the mean of the list of numbers is \$1/5\$ of the sum of the five numbers.

9

Choice.A

This fraction is not equal to the fraction we calculated

\$15/51\$

10

Choice.B

This option represents the fraction \$1/5\$, which is the correct answer based on our calculation. We found that the mean of the list of numbers is indeed \$1/5\$ of the sum of the five numbers

\$1/5\$

11

Choice.C

This is the mean of the list, not the fraction of the mean to the sum

\$11/5\$

12

Choice.D

This option represents the fraction \$1/55\$. While \$1/55\$ is a valid fraction, it doesn’t accurately represent the relationship between the mean of the list of numbers and the sum of the five numbers. Therefore, it’s not the correct answer

\$1/55\$

Answer

Option

B
