How do you turn 16.113846 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.113846 repeating into a fraction, begin writing this simple equation:

n = 16.113846 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (3846) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 16113846.3846 (equation 2)

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

1000000 × n = 16113846.3846
    100 × n = 16.113846
 999900 × n = 16112235

16112235999900 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 15 (the GCF - greatest common factor).

n = 16112235999900 = 16112235 ÷ 15999900 ÷ 15 = 107414966660. So,
