Answer 1

Step-by-step explanation:

the rational number between these will be..

by taking LCM of denominators.

we get...

20

hence...

-15/20 .............. -8/20

in between them we can get infinite rational numbers like...

-16/20,-17/20

etc..

Answer 2

Answer:

Given:

• -3/4 and -2/5​

To find :

• rational number between the two given numbers.

Pre-requisite knowledge :

Rational number : It is defined as a number which can be written in the form of p/q where q ≠ 0

Solving Question:

we are given the two numbers ,and find the a number which lies in between them.We can find and using $\dfrac{a+b}{2}$ or common way to make the denominator sme and find the answer.

Solution:

Here i am using the common way ;

first,make denominators same

using L.C.M  

$\implies L.C.M, \:of \:4\:and\:5\:is\:20\\\\\implies \dfrac{-3}{4}*\dfrac{5}{5}=\dfrac{-15}{20}\\\\and\\\\\implies \dfrac{-2}{5}*\dfrac{4}{4}=\dfrac{-8}{20}$

Thus, we can find the numbers

$\implies \dfrac{-9}{20},\dfrac{-10}{20},\dfrac{-11}{20},etc.\:are\:numbers.$
