Question

Insert 3 rational numbers between 7 and 9

Answer 1

7.5, 8, 8.5

Step-by-step explanation:

8 is between 7 and 9.

So, the first rational number is 8.

Now, for finding a number between 7 and 8,

1/2(7+8)

= 1/2(15)

=7.5

So, the second rational number is 7.5.

Now, for finding a number between 8 and 9,

1/2(8+9)

= 1/2(17)

= 8.5

So, the third rational number is 8.5.

Hence, three rational numbers between 7 and 9 are 7.5, 8 and 8.5.

Hope you understood.
