What is 1.25333... as a Fraction?

1.253 equals 9475 as a fraction.

How do you turn 1.253 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.253 repeating into a fraction, begin writing this simple equation:

n = 1.253 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (25). Multiply both sides by 10³ = 1000.

1000 × n = 1253.3 (equation 2)

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

1000 × n = 1253.3
 100 × n = 1.253
 900 × n = 1128

1128900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 12 (the GCF - greatest common factor).

n = 1128900 = 1128 ÷ 12900 ÷ 12 = 9475. So,

1.253 = 9475 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 9475 is also equal to 11975 when expressed as a mixed number.

The repeating decimal 1.253 (vinculum notation) has a repeated block length of 1. It is also represented as 1.25333... (ellipsis notation) which equals approximately 1.2533333 (decimal approximation)(*).

The recurring decimal 1.253 can be written as a ratio of two integers having 94 as the numerator and 75 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
