### Example Question #471 : Problem Solving

What is the least common multiple of 6 and 8?

**Possible Answers:**

**Correct answer:**

One easy way to find the least common multiple is to take the largest of the numbers given to you, and find its multiples.

8: 8, 16, 24, 32, 40, 48...

Now start with 8, and see if any of these numbers is divisible by 6. The first number that is divisible by 6 is the least common multiple of 6 and 8.

8: No

16: No

24: Yes

24 is the least common multiple of 6 and 8.

### Example Question #1 : How To Do Other Word Problems

How many whole numbers are between and ?

**Possible Answers:**

### Example Question #472 : Problem Solving

What is the next number in this progression?

18, 10, 2, -6

**Possible Answers:**

**Correct answer:**

This is an arithmetic progression. Therefore you must add or subtract a number to the number before it to arrive at the next number. We must find the difference between each number and apply it to the final number to find the next number in the series.** **

To start, take the second number and subtract the first number.

In this case it yields

Then take the third number and subtract the second number which results in

If the resulting number is the same you now know the difference between each number in the sequence and can apply the difference to each resulting number.

In this case the difference is

So we take the final number and add the difference to it to result with

Yielding an answer of

### Example Question #1 : How To Do Other Word Problems

**Possible Answers:**

**Correct answer:**

This tests your knowledge of scientific notation.

To solve you must move the decimal places to the right to the power of the ten.

In this case you must move the decimal place to the right 7 spaces from its original spot.

The solution is

### Example Question #2 : How To Do Other Word Problems

You have 5 types of meat, 3 different types of vegetables, and 8 different types of bread. How many different sandwiches can you make using only one of each ingredient?

**Possible Answers:**
