Answer:
the three rational numbers between 5 and 7 are 5.5, 6, and 6.5.
Explanation:
To insert three rational numbers between 5 and 7, you can divide the interval between 5 and 7 into equal parts. Here's how you can do it:
Find the difference between 7 and 5: 7 - 5 = 2.
Divide this difference by 4 (to insert three numbers): 2 / 4 = 0.5.
Now, add 0.5 successively to 5 to find the rational numbers:
5 + 0.5 = 5.5
5.5 + 0.5 = 6
6 + 0.5 = 6.5
6.5 + 0.5 = 7
