8 0

Answer:

27 boys

Step-by-step explanation:

The ratio of boys to girls is 3 to 6.  The total is (3+6) is 9.

Using the ratio of boys to total (3 to 9), we set it equal to the ratio of boys to total students (81)

3               b

---- = -------------

9          81

We can solve this using cross products.

3*81 = 9b

243 = 9b

Divide each side by 9

243/9 =9b/9

27 =b

There are 27 boys
