What is 24.41515... as a Fraction?

24.415 equals 8057330 as a fraction.

How do you turn 24.415 repeating into a fraction?

Detailed Answer:

Step 1: To convert 24.415 repeating into a fraction, begin writing this simple equation:

n = 24.415 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (15) and 1 digit in the non-repeating part (4). Multiply both sides by 10³ = 1000.

1000 × n = 24415.15 (equation 2)

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

1000 × n = 24415.15
  10 × n = 24.415
 990 × n = 24171

24171990 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 3 (the GCF - greatest common factor).

n = 24171990 = 24171 ÷ 3990 ÷ 3 = 8057330. So,

24.415 = 8057330 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 8057330 is also equal to 24137330 when expressed as a mixed number.

The repeating decimal 24.415 (vinculum notation) has a repeated block length of 2. It is also represented as 24.4151515... (ellipsis notation) which equals approximately 24.41515151515 (decimal approximation)(*).

The recurring decimal 24.415 can be written as a ratio of two integers having 8057 as the numerator and 330 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
