Answer: 25 = 0.4

From Decimal to Fraction

To convert a decimal to a fraction needs a little more work.

Steps	Example
First, write down the decimal "over" the number 1:	0.751
Multiply top and bottom by 10 for every number after the decimal point (10 for 1 number,100 for 2 numbers, etc):	0.75 × 1001 × 100
This makes a correctly formed fraction:	75100
Then Simplify the fraction:	34

From Fraction to Percentage

To convert a fraction to a percentage divide the top number by the bottom number, then multiply the result by 100%

0.05 = 1/20 as a fraction

Step by Step Solution

To convert the decimal 0.05 to a fraction follow these steps:

Step 1: Write down the number as a fraction of one:

0.05 = 0.05/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

0.05/1 = (0.05 × 100)/(1 × 100) = 5/100.

Step 3: Simplify (or reduce) the fraction:

5/100 = 1/20 when reduced to the simplest form.

0.45 = 9/20 as a fraction

Step by Step Solution

To convert the decimal 0.45 to a fraction follow these steps:

Step 1: Write down the number as a fraction of one:

0.45 = 0.45/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

0.45/1 = (0.45 × 100)/(1 × 100) = 45/100.

Step 3: Simplify (or reduce) the fraction:

45/100 = 9/20 when reduced to the simplest form.

1.3 = 13/10 = 13/10 as a fraction

Step by Step Solution

To convert the decimal 1.3 to a fraction follow these steps:

Step 1: Write down the number as a fraction of one:

1.3 = 1.3/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,

1.3/1 = (1.3 × 10)/(1 × 10) = 13/10.

(This fraction is alread reduced, We can't reduce it any further).

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 13/10 is also equal to 1 3/10 when expressed as a mixed number.

To convert fractions to decimals and millimeters and vice-versa use this formula:
