How do you turn 17.992 repeating into a fraction?

Detailed Answer:

Step 1: To convert 17.992 repeating into a fraction, begin writing this simple equation:

n = 17.992 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (2) and 2 digits in the non-repeating part (99). Multiply both sides by 10³ = 1000.

1000 × n = 17992.2 (equation 2)

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

1000 × n = 17992.2
 100 × n = 17.992
 900 × n = 16193

n = 16193900 (answer)

17.992 = 16193900 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 16193900 is also equal to 17893900 when expressed as a mixed number.
