mean= 6.875

Answer 2

Given :

• 5.1, 6.8, 8.2 and 7.4

To Find :

• The average of the given decimal numbers

Solution :

$\sf Average=\dfrac{Sum \: of \: all \: the \: Quantities }{Number \: of \: Quantities \: ( \: Addends \: )}$

$\sf Average=\dfrac{27.5}{4}$

$\sf Average= \: 6.875$

Therefore, the average of 5.1, 6.8, 8.2 and 7.4 is 6.875

Average :

• Average is a number which gives us the central or middle value.

• But, Average can be found only of like measures or similar quantities.

$\sf Average=\dfrac{Sum \: of \: all \: the \: Quantities }{Number \: of \: Quantities \: ( \: Addends \: )}$

• We can find the average in many situations, for example :-

- What are your average marks in Science?

- What is the average consumption of sugar in a week?
