120 people visit a maze.
80 are children, the rest are adults.
At the start of the maze you can turn left or right.
45 children turn left.
75 people in total turn left.
Complete the frequency tree.

1. **Fill in the first branches (Children/Adults):** - Total people = 120. - Children = 80. - Adults = Total - Children = 120 - 80 = 40. Write 80 in the Children circle and 40 in the Adults circle. 2. **Fill in the Children branches (Left/Right):** - Total children = 80. - Children who turn left = 45. Write 45 in the top-left final circle. - Children who turn right = Total children - Children who turn left = 80 - 45 = 35. Write 35 in the top-right final circle. 3. **Fill in the Adults branches (Left/Right):** - Total people turning left = 75. - Children turning left = 45. - Adults turning left = Total left - Children left = 75 - 45 = 30. Write 30 in the bottom-left final circle. - Total adults = 40. - Adults turning right = Total adults - Adults turning left = 40 - 30 = 10. Write 10 in the bottom-right final circle. 4. **Check your work:** The numbers in the final four circles should add up to the total number of people: 45 + 35 + 30 + 10 = 120. This is correct.
