There were 8 rows of picture frames at the store. there are 7 picture frames in each row. twelve picture frames are sold. how many picture frames are left at the store?

For this case we have The following data:

To know the amount of total frames in the store, we make a rule of three:

7frames ------> 1row

x ----------------> 8rows

Where x represents the number of frames in 8 rows, so, we have:

Thus, there is a total of 56 frames in the store.

Now, if 12 picture frames are sold, then:

Where and represents the number of frames of photo frames left in the store, after selling 12, subtracting is:

So, there are 44 frames left in the store.
