Question

Insert a rational number between each of the following pairs of numbers.

i) +6.236 and -1.438

ii) 3/10 and 2/11​

Answer 1

$(\star) \: \: \sf \frac{6.236 + ( - 1.438)}{2} \\ \\ \tt = > \frac{6.236 - 1.438}{2} \: = \frac{4.798}{2} \\ \\ = > \boxed{\red{2}. \red{399}}$

And,

$(\star) \: \: \sf \frac{ \frac{3}{10} + \frac{2}{11} }{2} \\ \\ \tt = > \frac{ \frac{33 + 20}{110} }{2} \: \: = \frac{33 + 20}{110 \times 2} \\ \\ \tt= > \boxed{ \frac{ \red{53}}{ \red{220}}}$

We Know,

▪A Rational number between any two number =

$\boxed{\bf \frac{( {1}^{st} \: \: number )+ ({2}^{nd} \: \: number )}{2} }$
