The ratio of boys to girls in a class is 3:5. There are 40 students in the class. How many students are boys?

The correct thing to do in this instanceis to take the total number of students (40) and divide them by the total parts of the ratios combined (3:5 so 3+5=8) 40/8 then gives us 5, which lets us know that every unit in the ratio is worth 5 students. Therefore, 3:5 boys:girls means (3*5):(5*5) which gives us 15 boys and 25 girls, nicely adding up to 40

Step-by-step explanation:
