Write a proportion for each question, using a question mark in place of the missing number. Use the proportion to find the missing number. Then check your answers in the Gizmo. (Note: The last one cannot be modeled in the Gizmo.) A: girls:total students= 3:7, girls = 12, Boys = ? / the proportion
B: boys:total students = 2:9, girls = 21, Boys = ? / the proportion
C: girls:boys = 2:3, boys = 225, Total students =

a. 74 degrees
