Question

Find the rational number between -2/5and1/2

Answer 1

$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

For finding rational number between any two fractional value following steps :

step 1: firstly add the both fractional value we obtain a new value say 'x'

step2: Then add 'x' with first original value to obtain a new value say 'y'

step3: Then add 'x' with second orginal value to obtain a new value say 'z'

step 4: Then add 'x' with resultant 'y' and 'z' to obtain a new resultant.This procedure going on and we obtain a new value further .

Rational number between -2/5 ans 1/2 are :

• 1st rational number

$= > - \frac{2}{5} + \frac{1}{2} = \frac{ - 4 + 5}{10} = - \frac{1}{10}$

• 2nd rational number

$= > - \frac{1}{10} ( + ) - \frac{2}{5} = \frac{ - 1 - 4}{10} = - \frac{5}{10}$

• 3rd rational number

$= > - \frac{1}{10} + \frac{1}{2} = \frac{ - 1 + 5}{10} = \frac{4}{10}$

• 4th rational number

$= > \frac{4}{10} ( + ) - \frac{5}{10} = - \frac{1}{10}$

• 5th rational number

$= > \frac{4}{10} ( + ) - \frac{1}{10} = \frac{3}{10}$
