How do you find how to make a decimal into a fraction?

Question

please show me examples?!? thanks!!

i meant to say how do you find an equivalent decimal to a fraction??!

i meant to say how do you find an equivalent decimal to a fraction??!

Answer 1

if it is 0.25, it is one-fourth bcuz it goes into 100, 4 times. if it is 0.50, it is one half. 0.75=three quarters, my algebra teach says to see how many times it goes into a 100, hope this helps

Answer 2

As an example, if you have to convert the decimal (i.e. .80) by hand, you could start by writing it as 80/100, and then find common denominators until you got 4/5. The function of an on-line tool, such as http://www.easycalculation.com/decimal-fraction.php is self-explanatory. Also, some graphic and scientific calculators have fraction to decimal; decimal to fraction converters built-in to them as basic functions.

Answer 3

The decimal system is a positional numeral system; it has positions for units, tens, hundreds, etc. The position of each digit conveys the multiplier (a power of ten) to be used with that digit—each position has a value ten times that of the position to its right.


so...

.1 = 1/10

.01 = 1/100

.001 = 1/1000

etc...

so once you get that down...

get a decimal, turn it using that say... .325 as an example

the farthest digit from the decimal point dictates the power f ten on the bottom (number of zeros after the 1 if you will.

.325 = 325/1000

now, most of the time you want to simplify it...you divide by the largest common factor...it wids up at 13/40...

so .325 = 325/1000 = 13/40...

hope that helped.

Answer 4

You move the decimal over to the right two spaces...

{0.10 would change to 10.}

Then you put that over 100

{10/100}

Then you reduce it to the smallest possible fraction by dividing the top and bottm by thier common denominator, in this cas it would be 10...

10 divided by 10 = 1
100 divided by 10 = 10

So that leaves you with 1/10

divide the top number by the bottom number and that gives you the equivelent decimal

ex: 7/15 = 0.4666666 or 3/10 = 0.30

Answer 5

.1 = 1/10
.01 = 1/100
.001= 1/1000
and so on.

.44467 = 44467/100000

.10 = 10/100, then reduce to 1/10
.25 = 25/100, then reduce to 1/4
.3333334 = 33/100= 1/3
.50 = 50/100, then reduce to 5/10, then to 1/2
.6666667 = 66/100 = 2/3
.75 = 75/100, then reduce to 3/4
.80 = 80/100, then reduce to 8/10 then to 4/5

And so on, and so on. Reduce what you can, leave the rest as the written fraction if you can't reduce it.

Answer 6

1/2 (one-half)
the equivalent decimal would be .50

3/4 (three-fourths)
the equivalent decimal would be .75

1/4 (one-fourth)
the equivalent decimal would be .25

Answer 7

its easy. every number after the decimal has a place value, so .9 is 9 tenths, or 9 over 10. .09 would be 9 hundreths, or 9 over 100

Answer 8

0.1 = 1/10
0.823 = 823/1000
0.500 = 500 / 1000 = 5/10 = 1/2
1.2334 = 12334 / 10000
0.25 = 25/100 = 1/4

And so on...

Answer 9

Use a calculator.
