Answer:by this process you will know that how to convert fraction to decimal

Example: What is 58 as a decimal ... ?

calculator

... get your calculator and type in "5 / 8 ="

The answer should be 0.625

No Calculator? Use Long Division to Decimal Places

Example: here is what long division of 58 looks like:

0.625

8 )5.000

0

5.0

4.8

20

16

40

40

0

In that case we inserted extra zeros and did 5.0008 to get 0.625

Another Method

Yet another method you may like is to 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: Convert 34 to a Decimal

Step 1: We can multiply 4 by 25 to become 100

Step 2: Multiply top and bottom by 25:

×25

right over arrow

34 = 75100

right under arrow

×25

Step 3: Write down 75 with the decimal point 2 spaces from the right (because 100 has 2 zeros);

Answer = 0.75

Example: Convert 316 to a Decimal

Step 1: We have to multiply 16 by 625 to become 10,000

Step 2: Multiply top and bottom by 625:

×625

right over arrow

316 = 1,87510,000

right under arrow

×625

Step 3: Write down 1875 with the decimal point 4 spaces from the right (because 10,000 has 4 zeros);

Answer = 0.1875

Example: Convert 13 to 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, 333

Step 2: Multiply top and bottom by 333:

×333

right over arrow

13 = 333999

right under arrow

×333

Step 3: Now, 999 is nearly 1,000, so let us write down 333 with the decimal point 3 spaces from the right (because 1,000 has 3 zeros):

Answer = 0.333 (accurate to only 3 decimal places !!)

Step-by-step explanation: hope it helps you
