Answer:
Step-by-step explanation:
5/7 = 45/63 Lcm of 9and 7 is 63
8/9= 56/63
so it is 46/63,47/63.... 55/63. Choose any two.
Step-by-step explanation:
Given :-
5/7 and 8/9
To find :-
Find two rational numbers between 5/7 and 8/9
Solution :-
Given two numbers are 5/7 and 8/9
We know that
Mean Method :-
Let a and b are two numbers then the rational number between them is (a+b)/2
The first rational number between 5/7 and 8/9
=> [(5/7)+(8/9)]/2
LCM of 7 and 9 is 63
=> [(45+56)/63]/2
=> (101/63)/2
=> 101/(63×2)
=> 101/126
The second rational number between 5/7 and 101/126
=>[(5/7)+(101/126)]/2
LCM of 7 and 126 is 126
=> [(90+101)/126]/2
=>(191/126)/2
=> 191/(126×2)
=>191/252
Answer:-
The two rational numbers between 5/7 and 8/9 are 101/126 and 191/252
Used formulae:-
Mean Method :-
Let a and b are two numbers then the rational number between them is (a+b)/2
