how do i find 7% of 14.95?? i ddnt understand wat she did.

[MathMammoth]

@888mexico My video has to do with using mental math in calculating percentages, but your problem has difficult numbers so I would use a calculator to do 0.07 x 14.95. Remember the "of" in "7% of 14.95" translates into multiplication. And 7% is written as a decimal (0.07).

[MathMammoth]

1.5 x 3 is correct. 1.5 is 10% of 15. And that times three gives you 30% of 15.
