Question

FIND FIVE RATIONAL NUMBERS BETWEEN 2AND 3 BY MEAN METHOD .

Answer 1

1st no. = 2+3/2=2.5 
2nd no. =2+2.5/2=2.25
3rd no .= 3+2.5/2=2.75
4th no.=2.5+2.25/2=2.375
5th no = 2.5+2.75/2=2.625
i m not sure whether it is correct but i think it may be correct . if my answer is wrog pls forgive me ...

Answer 2

Answer:

“Five rational numbers” between 2 and 3 are : 2.5, 2.25, 2.125, 2.75, 2.875 .

To find:

“5 rational numbers” between 2 and 3 using the mean method

Solution:

A “rational number” is a number which of the form a/b where a and b are integers.

Number 1: Take the “average of 2 and 3”  

$= \frac { 2 + 3 } { 2 } = \frac { 5 } { 2 } = 2.5$

Number 2: Take the “average of 2 and 2.5”

$= \frac { 2 + 2.5 } { 2 } = \frac { 4.5 } { 2 } = 2.25$

Number 3: Take the “average of 2 and 2.25”

$= \frac { 2 + 2.25 } { 2 } = \frac { 4.25 } { 2 } = 2.125$

Number 4: Take the “average of 3 and 2.5”

$= \frac { 3 + 2.5 } { 2 } = \frac { 5.5 } { 2 } = 2.75$

Number 5: Take the “average of 3 and 2.75”

$= \frac { 3 + 2.75 } { 2 } = \frac { 5.75 } { 2 } = 2.875$

Thus, “5 rational numbers” between 2 and 3 are : 2.5, 2.25, 2.125, 2.75, 2.875 .
