Since you gave two different equations I will solve both.
(1) 600 = 6 hundreds+ how many tens+ 0 ones
600 = 600 + 0 + 0
_____________________________________________________________
(2) 600 = how many tens + 0 ones
600 = 60 tens + 0 ones
600 = (60 x 10) + 0
600 = 600 + 0
Answers:
(1) 600 = 600 + 0 + 0 ones
(2) 600 = 60 + 0 ones
