Convert Fractions to Decimals
The simplest method is to use a calculator.
Just divide the top of the fraction by the bottom, and read off the answer !  
Example: What is ^{5}/_{8} as a decimal ... ? 

... get your calculator and type in "5 / 8 ="
The answer should be 0.625 
To convert a Fraction to a Decimal manually, follow these steps:
Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s. 
Step 2: Multiply both top and bottom by that number. 
Step 3. Then write down just the top number, putting the decimal point in the correct spot (one space from the right hand side for every zero in the bottom number) 
Example 1: Express 3/4 as a Decimal
Step 1: We can multiply 4 by 25 to become 100Step 2: Multiply top and bottom by 25:
×25  
3  =  75 
4  100  
×25 
Answer = 0.75
Example 2: Express 3/16 as a Decimal
Step 1: We have to multiply 16 by 625 to become 10,000Step 2: Multiply top and bottom by 625:
×625  
3  =  1,875 
16  10,000  
×625 
Answer = 0.1875
Example 3: Express 1/3 as a Decimal
Step 1: There is no way to multiply 3 to become 10 or 100 or any "1 followed by 0s", but we can calculate an approximate decimal by choosing to multiply by, say, 333Step 2: Multiply top and bottom by 333:
×333  
1  =  333 
3  999  
×333 
Answer = 0.333 (accurate to only 3 decimal places !!)
