Example Question #75 : Fractions

Convert this fraction to a decimal: 

 

(round to three decimals)

Possible Answers:

Correct answer:

Explanation:

To convert to a decimal, you must get the denominator to equal .  

Since 

, you must also multiple  by this.  

This results in a value of  and you move the decimal over two spaces to the left by dividing by  leaving you with .

Another approach is to set up the following long division.

by adding a zero we now can figure how many times seven goes into fourty.

    

 

    

    

 

Example Question #71 : How To Find The Decimal Equivalent Of A Fraction

What is the decimal equivalent for the fraction ?

Possible Answers:

Correct answer:

Explanation:

To find the decimal equivalent of a fraction, the method is to divide the numerator (the top number in a fraction that represents a part) by the denominator, (the bottom number of a fraction that represents the whole).

In this case, before dividing, you can reduce the fraction to simplest form, which if you divided the numerator and denominator by 3 (the greatest common factor), the fraction would be

 

To get the decimal equivalent you would divide 1 by 5.

You would need to first add a decimal point after the 1 and annex two zeroes:

By long division this is,

     

 

          

Example Question #77 : Fractions

In simplest form, which fraction is equivalent to 0.25?

Possible Answers:

Correct answer:

Explanation:

Although  is the fraction equivalent for 0.25 or twenty-five hundredths, the question is asking you to simplify the fraction.  

This is done by dividing both the numerator and the denominator by 25,

.

Therefore,  is the fraction equivalent of 0.25 in simplest form.
