Answer 2

Answer:

To Decrease 120 by 10%

we've to use

$\frac {n \: percentage}{100} \times n$

here N percentage refers to the %

and n is the number,from which we are finding the %

$\frac{10}{100} \times 120 = \frac{1}{10} \times 120 \\ = \frac{1}{1} \times 12 \\ = 1 \times 12 \\ = 12$

therefore the 10% of 120 is 12

and now

120-12=108

therefore the answer is 108
