Answer 1

Answer:

44 are left

Step-by-step explanation:

Answer 2

For this case we have The following data:

• 8 rows of picture frames

• 7 photo frames per row

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:

$x=\frac{(8*7)}{1}$

$x=\frac{56}{1}$

$x=56$

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

Now, if 12 picture frames are sold, then:

$y = 56-12$

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

$y = 44$

So, there are 44 frames left in the store.

Answer:

44 frames
