What is 1.4838383838383... as a Fraction?

1.483 equals 1469990 as a fraction.

How do you turn 1.483 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.483 repeating into a fraction, begin writing this simple equation:

n = 1.483 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 1 digit in the non-repeating part (4). Multiply both sides by 10³ = 1000.

1000 × n = 1483.83 (equation 2)

Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.

1000 × n = 1483.83
  10 × n = 1.483
 990 × n = 1469

n = 1469990 (answer)

1.483 = 1469990 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 1469990 is also equal to 1479990 when expressed as a mixed number.
