How do you turn 161.147 repeating into a fraction?

Detailed Answer:

Step 1: To convert 161.147 repeating into a fraction, begin writing this simple equation:

n = 161.147 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7) and 2 digits in the non-repeating part (14). Multiply both sides by 10³ = 1000.

1000 × n = 161147.7 (equation 2)

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

1000 × n = 161147.7
 100 × n = 161.147
 900 × n = 145033

n = 145033900 (answer)

161.147 = 145033900 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 145033900 is also equal to 161133900 when expressed as a mixed number.
