Only numbers should go in the columns for Payload Size and Packet Size. The sizes are in bytes. Don't forget to account for the FCS in your packet size. Make sure there are not extra spaces before or after your answers or Canvas will count it as incorrect.

Non-Payload Bytes sent are 1476(total) - 393 (payload) = 1083 bytes

1083 (non-payload) out of 1476(total) is 73.37 %

Non-Hello bytes sent are 1476(total) - 53(hello payload) = 1425 bytes

1425(non-hello) out of 1476(total) is 96.54 %
