How do you turn 1.33846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.33846 repeating into a fraction, begin writing this simple equation:

n = 1.33846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 1 digit in the non-repeating part (3). Multiply both sides by 10⁵ = 100000.

100000 × n = 133846.3846 (equation 2)

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

100000 × n = 133846.3846
    10 × n = 1.33846
 99990 × n = 133833

13383399990 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 = 13383399990 = 133833 ÷ 399990 ÷ 3 = 4461133330. So,

1.33846 = 4461133330 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 4461133330 is also equal to 11128133330 when expressed as a mixed number.
