4.32 = 108

25

= 48

25

as a fraction

To convert the decimal 4.32 to a fraction, just follow these steps:

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

4.32 = 4.32

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,

4.32

1

= (4.32 × 100)

(1 × 100)

= 432

100

.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(432,100) = 4. So,

(432÷4)

(100÷4)

= 108

25

when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 432

100

is also equal to 48

25

when expressed as a mixed number.
