To find the number of students who prefer math over science, you first need to calculate the actual number of students who prefer math and science individually.
0.72 of 50 students prefer math: 0.72 x 50 = 36 students prefer math
12% of 50 students prefer science: 0.12 x 50 = 6 students prefer science
So, there are 36 - 6 = 30 more students who prefer math over science in the survey.
