There's a thorough way and an easier way.
First, the thorough way:
Factor both the numerator and denominator.
120 = 8*15 = (2^3)*3*5
150 = 6*25 = 2*3*(5^2)
As a fraction, remove common terms from the numerator and denominator: 120/150 = (2^3)*3*5 / 2*3*(5^2) = (2^2)/5 = 4/5.
(Since the two in the denominator reduces 2^3 to 2^2, the three's cancel out and the five in the numerator cancels one of the fives in the denominator.)
Easier way:
120/150. Clearly they are both divisible by ten, so just chop off the trailing zeros: leaving 12/15. Now think of something that will divide both 12 and 15. Three comes to mind. Divide this out leaving 4 (12 divided by 3) in the numerator and 5 (15 divided by 3) in the denominator. Thus you have 4/5, same as we got before.

Take 120/150, both divisible by 30 120/3 = 4 150/30 = 5 == 4/5

First you can reduce to 12/15, or divide both terms by ten. Then look for what goes into both numerator and denominator, in this case, 3. Take that out of both, and you get 4/5. Check your work by plugging both 120/150 and 4/5 into your calculator. You should end up with .8, so you know your answer is good.

120/150 divided by 10= 12/15
12/15 divided by 3= 4/5
This is the lowest term

Start my romoving the 0 from the end of the numerator and the denomonator. Now you have 12/15 each of these will devide evenly by 3 so you have 4/5

Remove the 0 from both numerator and denominator
we get 12 / 15
Divide by the common factor i.e. 3, we get 4 / 5
Lowest term of the fraction is 4 / 5
In decimals it is 0.8
