2 answers:
Decreased by 25%
find 25% of 12 and decrease 12 by it
percent means parts out of 100
25%=25/100=1/4
'of' means multiply
25% of 12=1/4 times 12=3
decrease 12 by 3
12-3=9
answer is 9
first turn 25% into a decimal so it's easier to work with, the decimal for 25% is 0.25
then multiply the number by the decimal
12x0.25=3
then subtract your answer (3) from your starting number
12-3=9
12 dogs decreased by 25% leaves you with 9 dogs left.
if you are increasing, divide instead of multiply
