Percents

- Percent as "out of 100"

- Three equivalencies:
1/4 = .25 x 100 = 25%

- so from fraction to percent just 2 steps:
step 1: numerator divided by denominator = decimal value
step 2: decimal value x 100 = % value
that's it!

Using percents....

strategy 1:
use the definition of percents to make equivalent fractions
18% of people like chocolate ice cream best. How many people out of 200 like chocolate ice cream best?

18/100 = 36/200 so 36 people

strategy 2 (same problem);
multiply decimal equivalent by proposed total of people
0.18 x 200= 36 people
