When the right angles of the square get cut in half they both have to be 45.
The triangle problem starts at 51 seconds

This looks like 4 and 3/4
My best guess for this one is 3/4
This looks like 5 and ¼ or ½

Most of the time I would round the numbers to make guessing and checking easier. This time I’ going to be sneaky!
119,156 ends in a 6. That means that I can pick the last number of 3 of the state and add them to see if the number ends is 6.
Wisconsin ends 4. Vermont ends in 9 and Illinois ends in 3. 4+9+3=16.
Let’s check: 54,314 +9,249+55,593 = 119,156
