What are the only 4 possibilities for the ones-place digits of all primes greater than 5?
The possibilities for a digit in the ones place of a prime number greater than 5 are 1, 3, 7, and 9. If a 0, 2, 4, 6, or 8 is in the ones place, the number is divisible by 2, so it would not be prime. If a 5 is in the ones place, the number is divisible by 5, so it would not be prime.

Round 94 to the nearest ten?
Okay, what this means is to simplify the number 94 to the nearest ten. The 9 is in the tens place, and the 4 is in the ones place. So if you want to round to the nearest ten, you look at the number in the ones place; if the number in the ones place is any number from 1 to 4 then it gets rounded to zero. But if the number in the ones place is any number from 5 to 9, it is rounded up. So, if you look at 94, the four is in the ones place thus rounding 94 down to 90.
