What is 7.370606... as a Fraction?

7.3706 equals 243233300 as a fraction.

How do you turn 7.3706 repeating into a fraction?

Detailed Answer:

Step 1: To convert 7.3706 repeating into a fraction, begin writing this simple equation:

n = 7.3706 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (06) and 2 digits in the non-repeating part (37). Multiply both sides by 10⁴ = 10000.

10000 × n = 73706.06 (equation 2)

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

10000 × n = 73706.06
  100 × n = 7.3706
 9900 × n = 72969

729699900 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 3 (the GCF - greatest common factor).

n = 729699900 = 72969 ÷ 39900 ÷ 3 = 243233300. So,

7.3706 = 243233300 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 243233300 is also equal to 712233300 when expressed as a mixed number.

The repeating decimal 7.3706 (vinculum notation) has a repeated block length of 2. It is also represented as 7.37060606... (ellipsis notation) which equals approximately 7.370606060606 (decimal approximation)(*).

The recurring decimal 7.3706 can be written as a ratio of two integers having 24323 as the numerator and 3300 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.
