Forty percent of the students have elected to learn from home during the pandemic. The remaining students are divided into two equal groups, only one of which is physically in school on any day. What percent of students are present in school? Let's think first. Chain of thought:
100 - 40 = 60 percent of students are remaining. 60 / 2 = 30 percent are present in school.
Therefore, the answer is 30.
