Answer 2

Answer: There are 3+2=5 rows in total.

Step-by-step explanation:

Since we have given that

Number of black and white photos = 12

Number of color photos = 18 hours

We will first find the (H.C.F) of 12 and 18 to get "Number of photos in each row".

H.C.F. of 12 and 18 = 6

Therefore, there are 6 photos in each row.

Now, Number of row of color photos is given by

$\frac{18}{6}=3$

Number of rows of black and white photos is given by

$\frac{12}{6}=2$

Hence, there are 3+2=5 rows in total.
