A parking garage has6levels. Each levels has 15rows. Each row has the same number of parking spaces. There are 2,250 raking spaces in all.

Every row has 25 parking spaces.

Step-by-step explanation:

So you know, that the garage has got 6 levels.

You also know, that each level has got 15 rows.

Now, you need to multiply 15 rows times 6 levels. (15*6)

You will learn, than the whole parking garage has got 90 rows.

Now, you divide 2250 ranking spaces by 90 rows. (2250/90).

You will learn, that there are 25 spaces in every row.

That is the answer.
