Hi, Kevin.

Okay, what I think they're saying is to round to the greatest place value of the smallest number. For number one, the smallest number is 979 and the greatest place value for that is the hundreds place, so you would round all the numbers to the hundreds place. However, 979 doesn't round to 900, it should round to 1000 so that doesn't make sense.
