To divide 33 photos into two groups with a ratio of 4:7, first, sum the parts of the ratio. In this case, 4 (for the first group) + 7 (for the second group) equals 11 parts in total.
Next, calculate the value of one part by dividing the total number of photos (33) by the total parts of the ratio (11):
One part = 33 / 11 = 3
Now, to find out how many photos are in each group, simply multiply the number of parts for each group by the value of one part:
- For the first group (4 parts): 4 * 3 = 12 photos
- For the second group (7 parts): 7 * 3 = 21 photos
Thus, you can split the 33 photos into two groups of 12 and 21 photos, respectively, maintaining the desired ratio of 4:7.
