I believe the answer is 5.
200 divided by 25 is 8
40 divided by 8 is 5
Divide 33 photos into 2
groups.
The ratio of the said photo is 4 : 7
Now, we have the total number of photos which is 33, so let’s add the
ratio to get the total number of ratio
=> 4 + 7 = 11
=> 33 and 11, let’s divide
=> 33 / 11 = 3, now we have the number of photos in each group.
=> 4 x 3 = 12
=> 7 x 3 = 21
Thus the ratio of photos is 12 : 21
The answer would be 5
-2+7=5
-2+7 is like 7-2
