Answer 2

Question :-

Find the average of 4, 7/10 ,1, 3, 0 and 1/2

Solution :-

Given :

• 4, 7/10, 1, 3, 0, 1/2

Need to find :

• Average

Required Formula :

$\small{\red{\boxed{\rm{Average = \frac{Sum \: of \: all \: observations}{Number \: of \: all \: observations}}}}}$

Here, we have a data and need to find the average but in the data we have two fractions also then we add all the data also fractions (by average formula) and divide number of all the data.

$\sf:\longmapsto{ \frac{4 + {\frac{7}{10}} + 1 + 3 + 0 + \frac{1}{2} }{6} } \\ \\ \sf:\longmapsto{ \frac{8 + \frac{7}{10} + \frac{1}{2} }{6} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{ \frac{8 + \frac{24}{10} }{6} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{ \frac{8 + 2.4}{6} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{ \frac{10.4}{6} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto \boxed{ \sf{1.73}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Average = 1.73
