how do you convert decimals into fractions? ie. .25 into 1/4?

Answer 1

If they aren't repeating, then just place them over 10, 100, 1000, etc. matching the number of zeroes to the number of decimal places.

So .25 becomes 25/100

When you reduce it, it becomes 1/4

So 0.25 = 1/4

Here's another example:
0.375 = 375/1000 (notice three places equals three zeroes in 1000).
Dividing top and bottom by 125:
375/1000 = 3/8

So 0.375 = 3/8

Final example:
0.0625

625 / 10000 (remember four decimal places, not three)

Divide top and bottom by 625
625 / 10000 = 1/16

So 0.0625 = 1/16

Answer 2

First: change the decimal (.25) into a whole number > move the decimal two places to the right > 25

Sec: place 25 over 100 and reduce the fraction into its lowest term >

25/100 = 1/4

Answer 3

The decimal .25 is read (25, 100's)

So you write 25/100 and than factor out all common factors from the numerator and the denominator

25/100 = (5 x 5) / (5 x 5) x 4 the (5 x 5)'s cancel leaving you with 1 / 4

If the decimal was .375, you would read it as (375, 1000's)

375/1000 reduces to (5 x 5 x 5) x 3 / (5 x 5 x 5) x 8 the (5 x 5 x 5)'s cancel leaving you with 3/8

The key obviously is reading the decimal place, so's to know what multiple of 10 to divide by.

Answer 4

decimals are always factors of 10. in other words you start with 10 on the bottom of the fraction with a single digit decimal .1=1/10,

.3 =3/10 ect. for every digit you add to the top number, add a 0 to the bottom number. .33 =33/100, .125 =125/1000, ect. then you reduce the fraction to the smallest numbers on bottom and top that you can. 250/1000 =125/500=25 /100=5/20=1/4 .

Answer 5

.25 = 25/100 then simplify 25/25 = 1 100/ 25 = 4 so 25/100 = 1/4.

If you have a repeating decimal the process is more difficult.

Answer 6

Each decimal place is another "0"
So, for .25, it would be 100 (2 zero's because its 2 decimals out)
take the number and put it over what you come up with, so 25/100
.025 would be 25/1000 and so on
from there you reduce it down

Answer 7

.25=25/100 divide the numerator & denominator by all comon factors, in this case 5^2 or 25

(25/25)/(100/25)=1/4

Answer 8

.25 is equivalent to 25/100=1/4

Answer 9

If you know what the number 0.25 is actually called, it helps a lot. For example, 0.25 is not "zero point two five" as many people say it. 0.25 is "twenty five hundredths". That should tell you that the fraction form is 25/100 (also pronounced "twenty five hundredths"). Then, you can reduce if necessary. Here is a list:

0.1 = one tenth = 1/10
0.01 = one hundredth = 1/100
0.001 = one thousandth = 1/1000
etc.

Answer 10

0.25
= 25 / 100
(Put 1 for the dot -place and number of zeroes = number of digits to the right of dot-place, it is 100)
= 1/4
