At Still Bay Middle School, 3 out of 5 teachers have earned their masters degrees. If there are 30 teachers at the school, how many of them have earned their masters degrees?

18 out of 30 teachers have earned their masters degree.

Step-by-step explanation:

Lets represent the amount who have earned their masters degree using 3:5.

The total number is theoretically 5. The real total is given to us - 30. But 3 cannot be the number who have gotten their masters.

x:30 = 3:5 or x / 30 = 3 / 5

We know 30 ÷ 5 is 6. So, the answer should be 3 × 6 which is 18.

18:30
