To divide 33 photos into two groups with a ratio of 4:7, we first need to understand how to break down the total number of photos according to that ratio.
The ratio 4:7 means that for every 4 photos in the first group, there are 7 photos in the second group. To find the total parts of the ratio, we add the two parts together: 4 + 7 = 11 parts.
Next, we can calculate how many photos correspond to each part by dividing the total number of photos (33) by the total number of parts (11):
33 photos ÷ 11 parts = 3 photos per part
Now we can determine the number of photos for each group:
- Group 1 (4 parts): 4 parts × 3 photos/part = 12 photos
- Group 2 (7 parts): 7 parts × 3 photos/part = 21 photos
Thus, to achieve the ratio of 4:7, you can divide your 33 photos into two groups containing 12 photos and 21 photos, respectively.
