Aim # 12: How Are Fractions, Decimals, and Percents Related?
A New Approach?
Do NowDivide accordingly:
Do NowDivide accordingly: = 0.421052 . . .
Do NowDivide accordingly: = 0.421052 . . .
= 0.2
Do NowDivide accordingly: = 0.421052 . . .
= 0.2 = 0.04
Do NowDivide accordingly: = 0.421052 . . .
= 0.2 = 0.04 = 0.35
Do NowDivide accordingly: = 0.421052 . . .
= 0.2 = 0.04 = 0.35
= 0.0825
Do NowDivide accordingly: = 0.421052 . . .
= 0.2 = 0.04 = 0.35
= 0.0825 = 0.3333 . . .
Do NowDivide accordingly: = 0.421052 . . .

Minilesson:A commercial states “14 % of the dentists interviewed recommend Pest Toothpaste.”
That means 14 out of every 100 recommend the toothpaste.
Minilesson (con’t):
Percent helps us think within our decimal system.
Percent comes from “per cent” meaning “per every hundred”
[Like dollars per pound, mph, etc.]
The word “cent” is found in our money system (a great analogy for percent.”
The word “cent” is found in the words century and centimeters.
Minilesson (con’t):In general
Percent means “what part of one-hundred”
Minilesson (con’t):You convert fractions to N/100 by converting the original fraction to an equivalent fraction with denominator of 100.
X 5
X 5
= 15 %
Minilesson (con’t):You convert fractions to N/100 by converting the original fraction to an equivalent fraction with denominator of 100.
X 12.5
X 12.5
= 12.5 %
