How do you turn 16.1018 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.1018 repeating into a fraction, begin writing this simple equation:

n = 16.1018 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 3 digits in the non-repeating part (101). Multiply both sides by 10⁴ = 10000.

10000 × n = 161018.8 (equation 2)

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

10000 × n = 161018.8
 1000 × n = 16.1018
 9000 × n = 144917

n = 1449179000 (answer)

16.1018 = 1449179000 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 1449179000 is also equal to 169179000 when expressed as a mixed number.
