Of the 190 students in an elementary school, 57 students had perfect attendance during the second semester. What percent attendance that semester

The percent attendance for that semester was 30%.

Step-by-step explanation:

In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.

57 ÷ 190 = 0.3

Now, multiply 0.3 by 100 to get the percentage.

0.3 * 100 = 30

So, the percentage of the perfect attendance is 30%.
