?
Which of the following integers is divisible by
In order to find a number divisible by 6, you must find a number divisible by both of its factors — 2 and 3. Only even numbers are divisible by 2, so 81 is eliminated. In order to be divisible by 3, the sum of the digits has to be divisible by 3.
The sum of the digits of 316 is 3 + 1 + 6 = 10.
For 240, the sum is 2 + 4 = 6.
For 118, the sum is 1 + 1 + 8 = 10.
Only 6 is divisible by 3.

Which of the following rules makes the expression 
an integer?
Which of the following rules makes the expression
4 is already an integer, so we need to make sure x/10 is an integer too.
Multiples of 5 won't work. For example, 5 is a multiple of 5 but 5/10 isn't an integer. Similarly, if x/10 leaves a remainder of 5, x/10 isn't an integer. For example, 15/10 leaves a remainder of 5 and isn't an integer.
If x/10 has no remainder, then it must be an integer. For example, 10/10 and 20/10 both leave no remainders and simplify to the integers 1 and 2, respectively.

Apples are sold by whole bushels. You cannot purchase part of a bushel. There are 126 apples in a bushel.
Sam is a caterer who needs to bake 300 pies to sell at the county fair. If it takes 4 apples to make a pie, how many bushels must Sam order to ensure he has enough apples for his pies?

Sam is a caterer who needs to bake 300 pies to sell at the county fair. If it takes 4 apples to make a pie, how many bushels must Sam order to ensure he has enough apples for his pies?
Because Sam needs to make 300 pies, and each pie needs 4 apples, the number of apples he needs is
300 x 4 = 1200.
To determine how many bushels Sam needs, divide the total number of apples by the number of apples sold in a bushel.
1200 / 126 = 9.524
Because apples are sold by the whole bushel, Sam cannot order part of a bushel. In order to make sure he has sufficient apples, he will need to order 10 bushels.
