Question

find any five rational numbers which lie between the multiplicative inverse of 7/5 and additive inverse of -11/10

Answer 1

finding inverse

multiplicative inverse of 7/5 = 5/7 ( multiplicative inverse of any number is reciprocal { denominator to numerator and numerator to denominator }

additive inverse of -11/10 = 11/10 ( additive inverse of any number is changing the sign )
five rational numbers between 5/7 and 11/10
_____________________________________________________________

first make denominators equal 
5/7 * 10/10 = 50/70 ( multiply first number with second numbers denominator )
11/10 * 7/7 = 77/70 (multiply second number with first number denominator )

find numbers between 50 /70 and 77/70

therefore  the rational numbers between 5/7 and 11/10  are ( 51/70 , 52/70 , 53/70 , 54/70 ................................................... 75/70 , 76/70 )
