Enjoy!

3. The relationship
between fractions,

Now, on to
converting......
The Relationship
Between Them

4. Fractions and Decimals
To convert fractions into decimals, you
have to do this: numerator of the fraction
÷ denominator of the fraction
Converting to decimals is harder, so I’m
going to give you an example: 0.5. 0.
something means /10, so it is 5/10.
Then, simplify it. 0.0something means /
100, and so on......

5. Fractions and
Percentages
To convert fractions to percentages, you
have to change it into a decimal first, then
change it to a percentage. So if the
fraction is 5/10, then change it to 0.5,
then to 50%. Why 0.5 to 50%? Because it’s
5/10, so change the denominator to 100
and change the whole fraction (since %
means /100).
Percentages to fractions is similar. You
have to change the percentage into a
decimal, then back to a fraction.

6. Decimals and
Percentages
To convert decimals into percentages,
multiply the decimal by 100.
To convert percentages into decimals,
divide the percentage by 100 and take the
percentage sign away.
