Answer 1

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.

Answer 2

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
