What is 10.29888... as a Fraction?

10.298 equals 9269900 as a fraction.

How do you turn 10.298 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.298 repeating into a fraction, begin writing this simple equation:

n = 10.298 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 2 digits in the non-repeating part (29). Multiply both sides by 10³ = 1000.

1000 × n = 10298.8 (equation 2)

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

1000 × n = 10298.8
 100 × n = 10.298
 900 × n = 9269

n = 9269900 (answer)

10.298 = 9269900 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 9269900 is also equal to 10269900 when expressed as a mixed number.
