What is 88.9333... as a Fraction?

88.93 equals 133415 as a fraction.

How do you turn 88.93 repeating into a fraction?

Detailed Answer:

Step 1: To convert 88.93 repeating into a fraction, begin writing this simple equation:

n = 88.93 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 1 digit in the non-repeating part (9). Multiply both sides by 10² = 100.

100 × n = 8893.3 (equation 2)

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

100 × n = 8893.3
 10 × n = 88.93
 90 × n = 8004

800490 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 6 (the GCF - greatest common factor).

n = 800490 = 8004 ÷ 690 ÷ 6 = 133415. So,

88.93 = 133415 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 133415 is also equal to 881415 when expressed as a mixed number.

The repeating decimal 88.93 (vinculum notation) has a repeated block length of 1. It is also represented as 88.9333... (ellipsis notation) which equals approximately 88.933333 (decimal approximation)(*).

The recurring decimal 88.93 can be written as a ratio of two integers having 1334 as the numerator and 15 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.
