Converting decimals, percents and fractionsNOTES
Fraction to decimal
Numerator (top number) divided by denominator (bottom number)
Example
this would be 5 divided by 8 *it does not matter which is bigger, just top divided by bottom. That is also just how to type it into
calculator.
Decimal to percent
Multiple decimal by 100
Some students remember it by moving two decimal spots right
Why would it need to be 100?
Why two decimal spots?
*I remember this because it does not have a percent, which looks like a 100, it needs a 100. By multiplying it I am giving it a percent sign
Examples
Example
.18 X 100=18%. .09 X 100 =9%
1.86 moved two decimal spots would be186%
Percent to decimal
Divide percent by 100
Some students move it two spots left
*I remember because it has a % and I need to get rid of it divide it away
Example
43%/100 = .43. 6%/100 = .06
58% = .58
Decimal to fraction
The numbers in decimal will be the numerator
The denominator of the fraction will be the place value of the last digit in the decimal.

.06 = because the 6 is in the hundredths place
Simplify

Example
=.125 .125 X 100= 12.5%
