Answer:
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.
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%)
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%.
