What is 15.76222... as a Fraction?

15.762 equals 7093450 as a fraction.

How do you turn 15.762 repeating into a fraction?

Detailed Answer:

Step 1: To convert 15.762 repeating into a fraction, begin writing this simple equation:

n = 15.762 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (2) and 2 digits in the non-repeating part (76). Multiply both sides by 10³ = 1000.

1000 × n = 15762.2 (equation 2)

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

1000 × n = 15762.2
 100 × n = 15.762
 900 × n = 14186

14186900 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 = 14186900 = 14186 ÷ 2900 ÷ 2 = 7093450. So,

15.762 = 7093450 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 7093450 is also equal to 15343450 when expressed as a mixed number.

The repeating decimal 15.762 (vinculum notation) has a repeated block length of 1. It is also represented as 15.76222... (ellipsis notation) which equals approximately 15.7622222 (decimal approximation)(*).

The recurring decimal 15.762 can be written as a ratio of two integers having 7093 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.
