Question

find the average of 2.3 ,4.5 ,0.9 ,1.7 ,and 3.4
​

Answer 1

Here we have to find the average of the given numbers

the numbers are 2.3 ,4.5 ,0.9 ,1.7 ,and 3.4

sum of numbers = 2.3 + 4.5 + 0.9 + 1.7 + 3.4

= 12.8

total numbers = 5

To find the average we have to divide the s of the numbers by total numbers

average = sum of numbers/Total numbers

= 12.8/5

= 2.56

Hence, the average of the given numbers will be 2.56

Answer 2

To find: average of given numbers

Given data : $2.3, 4.5, 0.9, 1.7, 3.4$

Solution :

• Average is the arithmetic mean.

• It is the ratio of sum of all the numbers given in data to the total number of observations.

• Formula: $Average =\frac{\text { sum of all the observations }}{\text { total of observations }}$

• Here, sum of observations = $12.8$

• Total number of observations = $5$

• Substituting values in above formula,

       $\begin{array}{r}\text { Average }=\frac{12.8}{5} \\=2.56\end{array}$

Hence , average of given data is $2.56$ .
