How do you turn 152.7 repeating into a fraction?

Detailed Answer:

Step 1: To convert 152.7 repeating into a fraction, begin writing this simple equation:

n = 152.7 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7), so multiply both sides by 10¹ = 10.

10 × n = 1527.7 (equation 2)

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

10 × n = 1527.7
 1 × n = 152.7
 9 × n = 1375

n = 13759 (answer)

152.7 = 13759 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 13759 is also equal to 15279 when expressed as a mixed number.
