7 1/2
5 4/5
8.4
7.9

7 3/5

Answer 1

To find numbers that round to 7 when rounded to the nearest integer, we need to identify numbers that are in the interval [6.5, 7.5). Here are the numbers you provided that fit this criterion:

1. 7 3/10 (which is 7.3)
2. 7 1/2 (which is 7.5 - but this rounds to 8, so it doesn't count)
3. 6.0
4. 6 4/5 (which is 6.8)
5. 7 4/5 (which is 7.8 - but this rounds to 8, so it doesn't count)
6. 8.1 (this rounds to 8)
7. 6.1
8. 5 4/5 (which is 5.8)
9. 8.4 (this rounds to 8)
10. 7.9 (this rounds to 8)
11. 6.9
12. 7 3/5 (which is 7.6 - but this rounds to 8, so it doesn't count)

The numbers that round to 7 are:

• 6.0
• 6.1
• 6 4/5 (6.8)
• 6.9

Thus, three numbers that round to 7 are: 6.0, 6.1, and 6 4/5 (6.8).
