How do you turn 1433.67 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1433.67 repeating into a fraction, begin writing this simple equation:

n = 1433.67 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7) and 1 digit in the non-repeating part (6). Multiply both sides by 10² = 100.

100 × n = 143367.7 (equation 2)

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

100 × n = 143367.7
 10 × n = 1433.67
 90 × n = 129031

n = 12903190 (answer)

1433.67 = 12903190 as the lowest possible fraction.
