Explanation:

Step1: Find distance from 10 to 9.9

$|10 - 9.9| = 0.1$

Step2: Find distance from 10 to 9.99

$|10 - 9.99| = 0.01$

Step3: Compare distances (0.1 > 0.01)

Closest: 9.99

Step4: Find distance from 10 to 8.05

$|10 - 8.05| = 1.95$

Step5: Find distance from 10 to 8.5

$|10 - 8.5| = 1.5$

Step6: Compare distances (1.95 > 1.5)

Closest: 8.5

Step7: Find distance from 10 to 10.5

$|10 - 10.5| = 0.5$

Step8: Find distance from 10 to 10.05

$|10 - 10.05| = 0.05$

Step9: Compare distances (0.5 > 0.05)

Closest: 10.05

Step10: Find distance from 10 to 10.9

$|10 - 10.9| = 0.9$

Step11: Find distance from 10 to 10.99

$|10 - 10.99| = 0.99$

Step12: Compare distances (0.99 > 0.9)

Closest: 10.9

Answer:
