There are a number of ways to do this.
You can change 25% to a decimal - .25 and multiply this by 120.
You can also change 25% to a fraction - 1/4 and multiply this by 120. That is the same as dividing 120 by 4, which is 30.
So 25% of 120 is 30.

25% is 1/4
1/4 of 120 is 30.
25%= 25/100
25% of 120 = 120 * (25/100)
= 120 * 25/100
= 12*25/ 10
= 30
25% of 120=30
Just think of 25% like 25 cents or a quarter. It takes 4 quarters to make a dollar so just divide 120 by 4.
