What is 15.34888... as a Fraction?

15.348 equals 6907450 as a fraction.

How do you turn 15.348 repeating into a fraction?

Detailed Answer:

Step 1: To convert 15.348 repeating into a fraction, begin writing this simple equation:

n = 15.348 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 2 digits in the non-repeating part (34). Multiply both sides by 10³ = 1000.

1000 × n = 15348.8 (equation 2)

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

1000 × n = 15348.8
 100 × n = 15.348
 900 × n = 13814

13814900 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 2 (the GCF - greatest common factor).

n = 13814900 = 13814 ÷ 2900 ÷ 2 = 6907450. So,

15.348 = 6907450 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 6907450 is also equal to 15157450 when expressed as a mixed number.

The repeating decimal 15.348 (vinculum notation) has a repeated block length of 1. It is also represented as 15.34888... (ellipsis notation) which equals approximately 15.3488888 (decimal approximation)(*).

The recurring decimal 15.348 can be written as a ratio of two integers having 6907 as the numerator and 450 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.
