Let x be the number of seventh grade students.
The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.
The 16 2/23% of those students also have science class in the morning means:
16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning
30 students have math in the morning but not science in the morning
83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180
There are 180 seventh graders.
