You have 33 photos

You need to separate the photos in two groups for a ratio of 4:7

So what you do is add both numbers of the ratio

 \(4+7=11\)

Then divide the 33 photos by 11

\(33\)÷\(11=3\)

So that means that each number in the ratio is equivalent to 3 photos

Now multiply each ratio by 3

\(4*3=12\) and \(7*3=21\)

So the ratio of the photos are 12 to 21 or 12:21

Answer: ratio is 12 to 21 or can be written as 12:21
