9 students in the class play in the school band.

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3

In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.

You can also turn the percentage into a fraction, it's really up to preference.

30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
