Answer:
The Last Option: Billy, Bonnie, Benny, Bobby
Step-by-step explanation:
Bobby = 8.3
Bonnie = 840%
=> 840/100
=> 8.4
(8.4^2 = 70.56)
Billy = Square root of 71
=> Square root of 71 is between 8 and 9.
=> 8.4^2 = 70.56. So, the square root of 71 must be a larger number than 8.4.
=> Square root of 71 is 8.426.
Benny = 8 1/3
=> 25/3
=> 8.3333333333
If we order these greatest to least:
=> 8.426, 8.4, 8.3333333333, 8.3
=> Billy, Bonnie, Benny, Bobby
