Question

Three times a number is 27. What is the number?

Answer 1

The number is 9.

Explanation:

We can change this word problem into a number problem that looks like the following:

`3*x=27`

This makes it much easier to solve. Now we can do some basic algebra to solve for x, the number you're looking for.

`3*x=27`

`(3*x)/3=27/3`

`x=9`

This tells us that the number you're looking for is 9. We can check this by putting it back into the original problem.

3 times a number (9) equals 27.
3 times 9 equals 27.
`3*9=27`
This is correct and we have found and checked our answer!

Answer 2

`9`

Explanation:

Let's express the above statement using math.

Three times a number is 27

`" "darr` `" "darr` `" "darr` `" "darr` `""darr`

`" "3` `" "times` `" "n` `" "=` `" "27`

Now this is an equation that we can easily solve for `n`

`3n=27`

We divide both sides by `3` to solve for `n`

`cancel3/cancel3n=27/3`

`n=9`

Our number is then `9`.

This is true because Three times a number (`9`) is `27`
