(80pts) the ratio of the number of a's in the class to b's in the class was 2: 5. how many people got a's if there were 40 people who got b's?

Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class ()

Cross multiply

2 * 40 = 5 * A

80 = 5A

Isolate A by dividing 5 to both sides

80/5 = 5A/5

16 = A

If 40 people in the class got B's then 16 people got A's

Hope this helped!
