How do you turn 1432.47 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1432.47 repeating into a fraction, begin writing this simple equation:

n = 1432.47 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7) and 1 digit in the non-repeating part (4). Multiply both sides by 10² = 100.

100 × n = 143247.7 (equation 2)

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

100 × n = 143247.7
 10 × n = 1432.47
 90 × n = 128923

n = 12892390 (answer)

1432.47 = 12892390 as the lowest possible fraction.
