just divide the number after the decimal point by 1 followed by as many zeros as there are decimal places

example: write 0.25 as a fraction.

solution: there are two decimal places, so we divide 25 by 1 followed by 2 zeros, that is, 100.

so we have 0.25 = 25/100 = 1/4

you tell me. based on what i said earlier, what do you think it is?

5. Hello, shamonica!

Converting fractions to decimals . . . use long division.

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Example: $\frac{13}{20}$

Divide 13 by 20.
Code:
              0.6 5
---------
2 0 ) 1 3.0 0
1 2 0
-----
1 0 0
1 0 0
=====

Therefore: . $\frac{13}{20} \;=\;0.65$

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

However, most fraction do not "come out even."

Example: $\frac{4}{11}$
Code:
            0.3 6 3 6 ...
---------------
1 1 ) 4.0 0 0 0
3 3
---
7 0
6 6
---
4 0
3 3
---
7 0

Therefore: . $\frac{4}{11} \;=\;0.3636\hdots$

This can be written: . $0.\overline{36}\:\text{ or }\:0.36\tfrac{4}{11}$

haha, i read convert "decimal to fraction" as opposed to "fraction to decimal"

people usually ask how to go from decimal to fractions, so i was replying out of habit. thanks for looking out
