The moon revolves around its axis and orbits Earth in exactly the same time of about 27.32 days, relative to the Sun. This causes the moon to be constantly presenting the same face to the earth.
Just like any other sphere illuminated by any other flashlight, 50% of the moon's surface is always illuminated by the sun. But because the relative positions are always changing, we see different amounts of the lighted portion from earth. The complete cycle of 'phases' as seen from earth repeats with a mean (average) interval of 29.530589 days (29 days, 12 hours, 44 minutes, 02.9 seconds).

It takes 29.5 days for the moonto go through all the phases - from full moon to full moon. :)
29.53 days
About 29 and 1/2 days.
About twenty nine and one half days. (It's phases, not phrases).
27.3 days exactly.1 month
360 days
Because it takes the moon 29.53 days to go through the complete cycle of all of its phases, and half of that time is 14.77 days. (rounded)
It will take about 1 month for the moon to go through its phases
