'Hundred' in the Bible

Philip answered him, Loaves for two hundred denarii are not sufficient for them, that each may have some little portion.

Why was this ointment not sold for three hundred denarii and given to the poor?

And Nicodemus also, who at first came to Jesus by night, came, bringing a mixture of myrrh and aloes, about a hundred pounds weight.

and the other disciples came in the small boat, for they were not far from the land, but somewhere about two hundred cubits, dragging the net of fishes.

Simon Peter went up and drew the net to the land full of great fishes, a hundred and fifty-three; and though there were so many, the net was not rent.
