How do you turn 1436.157 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1436.157 repeating into a fraction, begin writing this simple equation:

n = 1436.157 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (7) and 2 digits in the non-repeating part (15). Multiply both sides by 10³ = 1000.

1000 × n = 1436157.7 (equation 2)

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

1000 × n = 1436157.7
 100 × n = 1436.157
 900 × n = 1292542

1292542900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 2 (the GCF - greatest common factor).

n = 1292542900 = 1292542 ÷ 2900 ÷ 2 = 646271450. So,

1436.157 = 646271450 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 646271450 is also equal to 143671450 when expressed as a mixed number.

The repeating decimal 1436.157 (vinculum notation) has a repeated block length of 1. It is also represented as 1436.15777... (ellipsis notation) which equals approximately 1436.1577777 (decimal approximation)(*).
