Convert from fraction to decimal number. To do it you need to divide the numerator by the denominator. Then, you get:

Let be "x" the number of bricks in the bag<em>.</em>
<em> </em>Based on the information given in the exercise, you can set up the following proportion:

Finally, you must solve for "x" in order to find its value. This is:

Answer:
6(6x-3)
=36x-18
Step-by-step explanation:
6(6x-3(
multiply 6 x 6 and 6 x 3
36x - 18
