Question

Mr. Smith has 18 girls and 22 boys in his math class. He has

26 students in the class that are wearing a school spirit shirt.
What percent of his class is wearing a school spirit shirt?

Answer 1

65% of Mr. Smith's students are wearing a school spirit shirt.

Explanation:

First, you need to find the total number of students in his class, which we can find by adding how many girls and boys Mr. Smith has.

`18 +22 = 40`

Now we know how many students Mr. Smith has total, so we can set up a proportion to find the percent. (Remember, we need to put X over 100, since percents are always out of 100%)

`(26)/(40) = (x)/(100)`

To find X (the number of students wearing a school spirit shirt), we need to multiply across (26 × 100), which is 2,600, and then divide by 40 on the other side, which then gives us the answer of 65%.
