Answer:
see below
Explanation:
106
The tens place is the 0, so we look at the ones place
Since 6 is 5 or greater we round the tens place up
0 will round to 1, and the ones places goes to 0
106 rounds to 110
We need a number less than 180 that will round up to 180 from the tens place
We look at the tens place, it has to be less than 8 by 1
17 x
The number must be 5 or greater to round the 7 up to 8
175, 176, 177, 178, 179 will work
We need a number greater than 180 that will round down to 180 from the tens place
We look at the tens place, it has to be equal to 8
18 x
The number must be 4 or less to leave the 8 alone
180, 181, 182, 183, 184
