What is 347.3... as a Fraction?

347.3 equals 10423 as a fraction.

How do you turn 347.3 repeating into a fraction?

Detailed Answer:

Step 1: To convert 347.3 repeating into a fraction, begin writing this simple equation:

n = 347.3 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3), so multiply both sides by 10¹ = 10.

10 × n = 3473.3 (equation 2)

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

10 × n = 3473.3
 1 × n = 347.3
 9 × n = 3126

31269 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 = 31269 = 3126 ÷ 39 ÷ 3 = 10423. So,

347.3 = 10423 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 10423 is also equal to 34713 when expressed as a mixed number.

The repeating decimal 347.3 (vinculum notation) has a repeated block length of 1. It is also represented as 347.333... (ellipsis notation) which equals approximately 347.33333 (decimal approximation)(*).

The recurring decimal 347.3 can be written as a ratio of two integers having 1042 as the numerator and 3 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.
