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

Aug 7, 2017

The number is 9.

#### Explanation:

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

$3 \cdot x = 27$

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

$3 \cdot x = 27$

$\frac{3 \cdot x}{3} = \frac{27}{3}$

$x = 9$

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.
$3 \cdot 9 = 27$
This is correct and we have found and checked our answer!

$9$

#### Explanation:

Let's express the above statement using math.

Three times a number is 27

$\text{ } \downarrow$ $\text{ } \downarrow$ $\text{ } \downarrow$ $\text{ } \downarrow$ ""darr

$\text{ } 3$ $\text{ } \times$ $\text{ } n$ $\text{ } =$ $\text{ } 27$

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

$3 n = 27$

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

$\frac{\cancel{3}}{\cancel{3}} n = \frac{27}{3}$

$n = 9$

Our number is then $9$.

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