What is 7.92666... as a Fraction?

7.926 equals 1189150 as a fraction.

How do you turn 7.926 repeating into a fraction?

Detailed Answer:

Step 1: To convert 7.926 repeating into a fraction, begin writing this simple equation:

n = 7.926 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (92). Multiply both sides by 10³ = 1000.

1000 × n = 7926.6 (equation 2)

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

1000 × n = 7926.6
 100 × n = 7.926
 900 × n = 7134

7134900 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 6 (the GCF - greatest common factor).

n = 7134900 = 7134 ÷ 6900 ÷ 6 = 1189150. So,

7.926 = 1189150 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 1189150 is also equal to 7139150 when expressed as a mixed number.

The repeating decimal 7.926 (vinculum notation) has a repeated block length of 1. It is also represented as 7.92666... (ellipsis notation) which equals approximately 7.9266666 (decimal approximation)(*).

The recurring decimal 7.926 can be written as a ratio of two integers having 1189 as the numerator and 150 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.
