In sixth grade, 12 out of 27 students have a dog. If there are 162 students how many would have a dog

The ratio is 12:27

Since there is a total of 162 students, you can divide 162 by 27 to see how/by how much larger 162 is to 27.

162/27 = 6

162 is larger than 27 by 6 times. To maintain the ratio, you can multiply 12 by 6. 6 (12:27)

12 · 6 = 72

72 students would have a dog
