Solution
- The square root of 87 is given as:
[tex]9.327...[/tex]
- This number is greater than 9, as a result, we can start counting the points between 9 and 10.
- These points are illustrated below:
- These numbers between 9 and 10 are:
9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9
- Based on the number we got from the square root of 87, we can see that the next best point we should consider is 9.3
- That is,
- We can graduate the space between 9.3 and 9.4 from 1 to 10 again and choose a point to represent 9.32. But because the next number after 2 is 7, it implies that the point we should choose should be closer to 9.33 than 9.32.
- Thus, we have:
- The above represents the best illustration of 9.327 i.e. √87, on the number line.
