Divide 33 photos into 2 groups so that the ratio is 4:7

The answer is 31

Let x = the number in the smaller group.

4/11 = x/33

Cross multiply and solve for x.

To divide 33 photos into two groups with a ratio of 4:7, we need to determine the size of each group.

Step 1: Calculate the total number of parts in the ratio. In this case, it is 4 + 7 = 11 parts.

Step 2: Find the size of each part by dividing the total number of photos by the total number of parts:
Size of each part = (Total number of photos) / (Total number of parts)
= 33 / 11
= 3

Step 3: Multiply the sizes of each part by the corresponding ratio values to determine the number of photos in each group:
Group 1 = 4 parts * 3 = 12 photos
Group 2 = 7 parts * 3 = 21 photos

Hence, you can divide 33 photos into two groups with a ratio of 4:7, where Group 1 has 12 photos and Group 2 has 21 photos.

let the two groups have numbers of 4x and 7x

then 4x + 7x = 33
11x=33
x = 3

So the two groups have a count of .....

Divide 33 photos into two groups si the ratio is 4 to 7
