What is 70.3666... as a Fraction?

70.366 equals 211130 as a fraction.

How do you turn 70.366 repeating into a fraction?

Detailed Answer:

Step 1: To convert 70.366 repeating into a fraction, begin writing this simple equation:

n = 70.366 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (36). Multiply both sides by 10³ = 1000.

1000 × n = 70366.6 (equation 2)

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

1000 × n = 70366.6
 100 × n = 70.366
 900 × n = 63330

63330900 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 30 (the GCF - greatest common factor).

n = 63330900 = 63330 ÷ 30900 ÷ 30 = 211130. So,

70.366 = 211130 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 211130 is also equal to 701130 when expressed as a mixed number.

The repeating decimal 70.366 (vinculum notation) has a repeated block length of 1. It is also represented as 70.36666... (ellipsis notation) which equals approximately 70.3666666 (decimal approximation)(*).

The recurring decimal 70.366 can be written as a ratio of two integers having 2111 as the numerator and 30 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.
