The statement is true
Step-by-step explanation:
Most proofs are direct proofs becaue theorums & postulates prove them true straightforwardly :)
Let's see -
Let's solve the first question step-by-step
(WARNING - This may confuse you a little)
1)
4 1/8 + 2 1/3
= 33/8 + 2 1/3
= 33/8 + 7/3
= 155/24
= 6 11/24 --------> Note that this is your final answer and it already looks simplified down to its simplest form. :)

2) This equation, as far as solving it, is no different than number 1. Let's go for it!
5 17/18 - 2 2/3
= 107/18 - 2 2/3
= 107/18 - 8/3
= 59/18
= 3 5/18 -----------------> This is your final answer, and, as before, it looks simplified enough.
