What is 48.21444... as a Fraction?

48.214 equals 43393900 as a fraction.

How do you turn 48.214 repeating into a fraction?

Detailed Answer:

Step 1: To convert 48.214 repeating into a fraction, begin writing this simple equation:

n = 48.214 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (4) and 2 digits in the non-repeating part (21). Multiply both sides by 10³ = 1000.

1000 × n = 48214.4 (equation 2)

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

1000 × n = 48214.4
 100 × n = 48.214
 900 × n = 43393

n = 43393900 (answer)

48.214 = 43393900 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 43393900 is also equal to 48193900 when expressed as a mixed number.
