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!

#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#
